Well, guido ... you've just volunteered yourself to write aFreeBSD-specific installation doc, haven't you? :)
Our docs are mostly RH 6.2 Linux specific. Write us good docs that allow folks to simply and reliably install under FreeBSD and we'll say "our docs are written with RH 6.2 linux and FreeBSD in mind".
That's all it takes.
For the PG version of OpenACS, anyway. Those wanting to run Oracle with OpenACS 4.x will have to deal with linux compatibility libs and the attendant and aforementioned problems they seem to have.
Oracle's direct support of Linux rather than *BSD is why I've stuck with Linux, I gotta be able to run both Oracle and PostgreSQL on the same box. Oracle's hassle enough without begging for trouble and straying from their reference platform.
there is also this nasty problem with EXEC that jacques mentions.
Have you tried the tcl exec command to see if it works correctly on your installed aolserver? We won't be able to run OpenACS 4.x on Free BSD without a fix for this problem as the bootstrapper relies on EXEC to load datamodels, etc.
