Thank you for explaining this!  On FreeBSD Mono is installed
into /usr/local but GTK# lives with Gnome in /usr/X11R6 as do all GTK#
dependent apps.  I've had to patch most apps locally while packaging to
handle this.

Additionally, would it be possible for Mono to take into consideration
multiple GAC locations via a config file instead of through an
environmental variable?  I used a shell script wrapper as a temporary
solution to set additional locations with MONO_GAC_PREFIX and now we've
simply added /usr/X11R6 to the search path in mono/metadata/assembly.c .

This would really help packagers who have certain filesystem hierarchy
requirements to deal with.
