#
# 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
#		  (for example: perl5.24)
# 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, run or test 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.
