The code does not presently support the use of arbitrary environment 
variables and I'm not sure if there might be any security implications 
from doing so.

However, if you want your shipped copy of fontconfig to use an 
environment variable, then you can write a quick and dirty hack to, for 
instance, FcConfigAddDir.  Add something like the following lines:

	if (strcmp(d, "$CUSTOM_FONT_DIR") == 0)
		d = (FcChar8 *) getenv ("CUSTOM_FONT_DIR");

I think that'll work for your case.
