# This helper does the required steps to be able to build and install
# perl modules that use MakeMaker into the correct location.
#
# Required vars to be set by a template:
#
# 	build_style=perl-module
#
# Optionally if the module needs more directories to be configured other
# than $XBPS_BUILDDIR/$wrksrc, one can use (relative to $wrksrc):
#
#	perl_configure_dirs="blob/bob foo/blah"
