Read /usr/ports/Mk/bsd.perl.mk. I think mostly many of the variables 
contained within may be set in /etc/make.conf and can be picked up at build 
time by make. Particularly interesting were PERL_VERSION, PERL_PORT, and 
USE_PERL, for example. Reading down into the contents will point to how the 
variables get used.
