FreeBSD users....

Gyach will compile properly with FreeBSD if set the proper location of
gtk-config in the GTK_CONFIG environment variable.

For instance, if gtk-config is /usr/X11R6/bin/gtk12-config and you are
running bash, you can just do this:

GTK_CONFIG=/usr/X11R6/bin/gtk12-config ./configure

then run "make" as normal.
