I thought a little bit about this issue (someone at x11@ should correct
me if something doesn't work as expected):
Running the FreeBSD fc-cache program should be enough (it creates the
fonts.cache-1 files). I don't think we need to run the linux fc-cache
program (maybe we should remove the run of fc-cache when we install the
linux-fontconfig port). I can't identify something else the fc-cache
program does than creating the fonts.cache-1 files, at least the
man-page doesn't mentions more. Since nobody will be able to run a linux
X11 program without an X server, and since fonts are a server side issue
(at least they where the last time I looked at this topic), we should be
on the safe side to not depend upon any fonts on the linux side.
BTW: not all font ports run fc-cache:
grep -R fc-cache /usr/ports/x11-fonts | grep -v fontconfig

If it doesn't check them automatically, the pango-querymodules program
will not run.
Bye,
Alexander.
