After moving from 11.10 to 12.04, I need to install some additional fonts. They are pcf fonts in various directories of the form "term11.pcf" and have a fonts.dir file and a fonts.alias file for each directory of fonts.

How do I install these so that Ubuntu can find and use them? I found a thread about this where a fellow had written a script to install them. I used that script and installed the fonts but Ubuntu does not use them.

I need them for an old application that is written in C with X-Windows libraries.

Any ideas?
