You don't understand my reply. Likely (I can't say for sure) FreeBSD doesn't provide a script comparable to NetBSD's build.sh, at least I had no success when googling. The second link posted by me is a tutorial on how to set up "a cross compiler (gcc) for freebsd under linux", which is a starting point, an alternative to a script that automagically sets up "everything".
