# Provide support to use perl5
#
# 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 (major.minor without patchlevel)
#
# 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=5.14.4 would give
#				  a PERL_LEVEL of 501404. 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: mach).
# PERL_PORT		- Name of the perl port that is installed
#				  (value: perl5.14)
# SITE_PERL		- Directory name where site specific perl packages go.
#				  This value is added to PLIST_SUB.
# SITE_ARCH		- Directory name where arch site specific perl packages go.
#				  This value is added to PLIST_SUB.
# USE_PERL5		- If set, this port uses perl5 in one or more of the extract,
#				  patch, build, install or run phases.
#				  It can also have configure, modbuild and modbuildtiny when
#				  the port needs to run Makefile.PL, Build.PL and a
#				  Module::Build::Tiny flavor of Build.PL.
