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 ------------------------------- amg -at- iri -dot- columbia -dot- edu Johann Cohen-Tanugi wrote: > Sorry for the preceding mis-threaded version.
