Yeah... seems you are correct.

I commented those lines out and restored the rest of my make.conf. 
Buildworld segfaulted in the same place again.

Here's the make.conf that caused the problem:
--------------------------------------------------------------------
PERL_VER=5.8.5
PERL_VERSION=5.8.5
PERL_ARCH=mach
NOPERL=yo
NO_PERL=yo
NO_PERL_WRAPPER=yo

Any other pointers on which directives are to blame?

Thanks again,
