[Bug 1266605] Re: matplotlib crashes after recent tcl/tk update

[David Murphy]

Hi Sandro,

Are you sure? After an initial apt-get purge, I checked, and indeed
/usr/local/lib/python2.7/dist-packages/matplotlib/ remained in place as
you imply. I then moved matplotlib* in the above directory out of the
way, and sure enough python then fails to import. When I re-install
however, it is placed in exactly this directory:

david at spengler:~$ python -c "import matplotlib; print matplotlib"
Traceback (most recent call last):

ImportError: No module named matplotlib
