Bundle matplotlib with Mantid

[Martyn Gigg]

We already bundle matplotlib on Windows (as a holdover from IPython) but it was agreed by the ​TSC to bundle matplotlib on OS X and add dependencies to the Linux packages.

[Martyn Gigg]

The Linux packages already seem to have the required dependencies

[Martyn Gigg]

This ​commit was to the ​3rdpartylibs-mac repository:

Add matplotlib and dependencies for OS X 10.8

Refs #10369

[Martyn Gigg]

The 3rdpartylibs repositories don't have branches so the code is actually already merged.

For testing it requires OS X so please take the latest successful build from ​http://builds.mantidproject.org/job/develop_clean/label=osx-10.8-build/ and test that the package now includes matplotlib. For testing please be mindful of the warnings here: http://www.mantidproject.org/MantidPlot:External_Python_Plotting_Package.

Unfortunately this didn't work.

ImportError: matplotlib requires pyparsing
  at line 1 in 'New script'
  caused by line 125 in '/Applications/MantidPlot.app/Contents/MacOS/matplotlib/__init__.py'

I tried with the clean build from Monday 27th October 2014.

[Martyn Gigg]

It looks like the cmake bundle didn't copy over pyparsing.py. I'll have another look.

[Martyn Gigg]

Add a rule for installing files for bundled OS X Python packages.

That should do it. This time there is a ​branch to merge in the main code repository.

[Owen Arnold]

Different error obtained now.

[Martyn Gigg]

I have fixed the problem with the library reference in the 3rdpartylibs-mac repository in this ​commit.

The next develop_clean build should contain the fix.

[Owen Arnold]

Merge remote-tracking branch 'origin/feature/10369_bundle_matplotlib'
