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.

Maybe the files just didn't get written into your directory, since
matplotlib bailed out at the first failure.
