Marc has still a problem, because the lazarus IDE can't set the target processor to ppc yet.
Locate this script, it is probably in /usr/lib/fpc/1.0.10 or /usr/lib/fpc/1.0.11.This script creates fpc.cfg file.run it like this.cd /the/dir/with/the/samplecfg./samplecfg .
So the problem seem to be that it couldn't create the fpc.cfg in /etc (that is strange anyway).
