# USE_PERL5		- Says that the port uses perl5 for building and running.
# USE_PERL5_BUILD	- Says that the port uses perl5 for building.
# USE_PERL5_RUN		- Says that the port uses perl5 for running.
# PERL5			- Set to full path of perl5, either in the system or
#				  installed from a port.
# PERL			- Set to full path of perl5, either in the system or
#				  installed from a port, but without the version number.
#				  Use this if you need to replace "#!" lines in scripts.
# PERL_VERSION	- Full version of perl5 (see below for current value).
# PERL_VER		- Short version of perl5 (see below for current value).
# PERL_LEVEL	- Perl version as an integer of the form MNNNPP, where
#					M is major version, N is minor version, and P is
#					the patch level. E.g., PERL_VERSION=5.6.1 would give
#					a PERL_LEVEL of 500601. This can be used in comparisons
#					to determine if the version of perl is high enough,
#					whether a particular dependency is needed, etc.
# PERL_ARCH		- Directory name of architecture dependent libraries
#				  (value: ${ARCH}-freebsd).
# PERL_PORT		- Name of the perl port that is installed
#				  (value: perl5)
# SITE_PERL		- Directory name where site specific perl packages go.
#					This value is added to PLIST_SUB.
