	do we really want to do this?

BUILD_DEPENDS+= ${PERL5}:../../lang/perl5-base
	by doing this, the Makefile will check /usr/pkg/bin/perl.
	if we try to build the package on a system with perl shipped by
	default (like /usr/bin/perl), it will pull unnecessary dependency.

	===> Required file /usr/pkg/bin/perl: found

BUILD_DEPENDS+= perl:../../lang/perl5-base
	by doing this, it will try to find perl from the search path.
	it will build happy with /usr/bin/perl or something like that.

	===> Required executable perl: /usr/pkg/bin/perl found
