The replies have been helpful, but I'm still trying to figure out where
the problem lies, but I have noticed that matplotlib-0.90.1 apparently
doesn't use ttconv. I have this version installed at home and am able to
generate poscript without a problem. Are you able to tell which package
is complaining about the undefined symbol(s)?
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 (!) But I
would prefer to be able to generate .ps or .eps, even if I lose the
capability of using LaTeX for plot labels, e.g.
Best wishes,
Arthur
