* openmpi: flake8 fixes

* Update the krell institute products to use the latest features of spack for building on cluster platforms.

* Address travis error messages and resubmit the pull request.

* Update the contents of openspeedshop package.py so it passes the flake8 tests.

* Fix flake8 error-whitespack issue in mrnet package.py file.

* Add updates based on spack reviewer feedback.

* More fixes based on comments from reviewers.  Switch using extend to using append, remove additional setting of PATH and LD_LIBRARY_PATH that should not be required due to RPATH.

* More review related changes.  Update MPIOption.append lines and take out xercesc references.

* Create a base options function for common openspeedshop base cmake options to reduce redundencies.

* Add libxml2+python depends on to get around issues with the libxml2 package file.

* veclibfort: add new package

* veclibfort: add a small test

Add a package for ant, a java build tool.

Add a package that installed the pre-built maven distribution.

I've given up, for now, on building maven from source.  That processed
stumbled on two points before I gave up:

1. It downloaded several hundred .{pop,jar} files and I despaired of
   figuring out some way of mirroring and checksumming them; and

2. It exploded complaining about too many unacceptable license files,
   which seems odd in its own source tree.

Perhaps someone with more Java fu that I admit to can figure it out.
In the meantime, this is useful.

* libsodium: add latest versions, fix old versions

older versions of libsodium were added to an "old" subdirectory

* zeromq: add 4.1.4

prerequiste for the latest develop version of flux

Pkg-config depends on glib which depends on pkg-config. As a result,
pkg-config used to build glib internally. However, this fails on Mac.
Building pkg-config with an internal glib is now a variant, turned on
by default, and required to build glib.

* Add patch allowing GCC 6 to compile GCC 5

* Expand patch version range

* Tells boost explictly about libraries and headers

Ideally, bjam would determine the libraries and headers from the
executable. But it doesn't. This rigs a best guess for python libraries
and headers.

* Move glob import to top of file

* variable name change: alllibs --> all_libs

* Use dso suffix rather than hard-coded string

* Use only MAJOR.MINOR when setting up python in bjam

do_install : allow for an arbitrary number of phases

* Fixed a bug causing config-specified compiler flags to be ignored.
Updated the compiler config so all flags are in a separate section.

* Updated the documentation for the `compilers.yaml` file spec.

* Implemented basic testing for the 'flags' section of compiler config.

* Fixed a few minor problems with the manual compiler config documentation.

* Adds new versions to eigen

* Reorder versions from oldest to newest

* mumps: Add support for Intel compiler and insure both lapack and blas libraries are passed to the examples

Likely it was not discoverged before that the examples require both lapack and blas libraries because it
was tested with Openblas which is one large library containing everything.

* flake8 fix.

* Created the initial version of the 'OpenSceneGraph' package.

* Added 'zlib' as a dependency and linked it during the build step.

* Fixed a few minor PEP8 style violations in the 'OpenSceneGraph' package.

* Added cmake as a build dependency and improved the build procedure.

* Made a few important argument updates to improve package compatibility.

* Fixed up a few remaining style issues in the 'openscenegraph' package.

* Added a description for the 'openscenegraph' package.

* Fixed a bug that was causing some 'openscenegraph@3.2.3%gcc' installs to fail.

* Fixed a number of small issues with the 'openscenegraph' package.

* Removed a number of superfluous flags from the 'openscenegraph' install.

The texlive tarball, install-tl-unx.tar.gz is unversioned and changes
periodically.  When it does, the digest needs to change too.  This does
that.

* Don't clear LD_LIBRARY_PATH and friends from compiler wrappers

* remove debugging print
