I go into /BETA1/usr/ports/ports-mgmt/synth , run
env MAKESYSPATH make all-depends-list
and then it seems to work correctly with no syntax error in
/BETA1/usr/share/mk/bsd.compiler.mk

Maybe I need to file a bug.

What happens if src, ports and doc trees are installed on an NFS share, where there would be no FreeBSD installation?
