That is correct. ttconv is a tool to convert and subset Truetype fonts to Postscript fonts for embedding in Postscript files. > I have this version installed at home and am able to > generate poscript without a problem.

These sorts of messages are very common when you compile something on one version of gcc (libg++) and then run on a machine with another version of libg++. Did you obtain binaries for matplotlib 0.91.2 somewhere, or did you compile from source? > If I downgrade (at work) I will probably lose some capabilities, since > the file size of 0.91.2 is more than twice that of 0.90.1 (!) I suspect most of the file size difference is due to the inclusion of the STIX math fonts. There weren't huge amounts of code added between 0.90 and 0.91.
