We could update the makefile so that make clean really cleans up the installation "junk" before installing a new version. I personnally would find it very useful, but the makefile needs a bit of love. Typically "make" would run make clean and make install.
I can work on that if people agree that having a nice makefile would be useful.

Cheers,

Same with me. I had a stale pyparsing.pyc file in the MPL source directory (presumably from an old MPL version) whose version # was too old. When mpl tried to 'import pyparsing', it found that version, and raised an error. Of course, if I tried "import pyparsing; print pyparsing.__version__" from my home directory, python found a more recent pyparsing. So the error message was a little confusing.

I only think this is going to effect people building from the Git source, who have the old pyparsing.pyc file.

Just checked out rc5 from git and did an install, and ran into a pyparsing version check issue.

What was the issue?  Is it that you had 2.0.1 which rc5 still considers to be incompatible with Python 2?  I'd like to know specifically what happened in case there's a deeper issue.



It claimed I didn't meet the minimum pyparsing version needed when I tried importing matplotlib after installing from source. However, importing pyparsing on its own yielded a version slightly above the minimum (I forget the actual numbers).  I had also just came from an build of an older version of matplotlib.
