[Yt-dev] install script error?

[Matthew Turk]

Geoffrey,

The line you cite in the install script is set up to warn you whether
or not any fontfile caches exist.  If it finds them, it suggests that
you delete them -- it's designed to prevent what it looks like has
happened here.  :)

Maybe you could try removing the cache, and seeing that helps?

rm ~/.matplotlib/*.cache
