That was me, actually. I forgot to mention that I had a local hack in
bsd.port.mk to fix a little recursion problem with USE_GCC30 :)
The problem is that USE_GCC30 really means "make this port depend on
gcc30, and set CC=gcc30". But adding that flag to /etc/make.conf makes
gcc30 depend on gcc30, so during the find-dependencies stage, you get
recursive makes. I added code for a WITH_GCC30 flag that simply sets
CC=gcc30 without adding the dependency, and put WITH_GCC30=YES in
/etc/make.conf.
