That's a font that probably came with a TeX distribution and somehow got
installed in your font library.

Failing on this line is a bug in matplotlib, since the AFM spec says
that bounding-box coordinates are "numbers", not "integers". Apparently
not many AFM files use that precise bounding boxes, since we haven't run
into this before.
I don't know how the MacPorts packaging system would react to modifying
installed files, but I imagine that applying the attached patch should
fix this.
Also, after some curiosity, I realised the file ~/.matplotlib/
fontList.cache doesn't exist. In fact, the ~/.matplotlib directory is
empty, there aren't even any hidden files. On my other computer,
matplotlib works fine and the ~/.matplotlib directory contains three
files: fontList.cache, fontManager.cache and tex.cache.
Maybe the files just didn't get written into your directory, since
matplotlib bailed out at the first failure.
afm-bbox.patch (634 Bytes)
Hi Jouni,
Wow, that worked a treat. Thank you very much! Maybe you should post that to the -devel mailing list, too!
On the computer that this bug didn't occur, the ~/Library/Fonts directory is completely empty! I wonder where it is looking for lcmssi8.afm if it isn't in ~/Library/Fonts
Yeah I didn't want to play around with the installed files Macports creates, so I installed matplotlib from svn and, also since I don't know how to apply a patch, I just edited the afm.py to make your changes. This worked fine, and I no longer get the error!
Also, as I now have produced a graph (just a sin wave) as a test, the ~/.matplotlib directory contains some files (fontList.cache and tex.cache). It seems as though these files are created to aid in the speed of producing plots in the future by saving previously produced text output.
Thank you very much, Jouni!
Regards,
--Damon
