I run the latest release-version on Linux.

The thing is, the truetypefonts works fine when I do normal plots (not using
the gnome2 canvas).
I have the same result from the grep (only with another PATH that I have
specified). In that dir I have placed fonts
FreeMono*, FreeSans*, FreeSerif*. I did download these manually and place
them there, but again, it works fine when plutting without gcw (I get smooth
truetype/"freetype" fonts on the labels).
This is the main reason for me suspecting something gcw specific, does gcw
expect some different fonts or odoes it have any other compile parameters
that I may have missed?
