Hello,
Just in case that anybody is interested - I put a Squeak 2.2 VM for the latest FreeBSD (3.0-RELEASE) into ftp://alix.inria.fr/pub/incoming/. In addition, I placed a copy in http://www.apfel.de/~jesse/squeak/. Both directories also contain the diff file for GNUmakefile.conf that I used.
Regards, Roland
