>Description:
bsd.ruby.mk's RUBY_SHEBANG_FILES is very nifty and I want to use it
for non-ruby scripts.

>How-To-Repeat:

>Fix:
The following patch would be incomplete but better than nothing.

USE_REINPLACE=	yes
post-patch:
	${REINPLACE_CMD} -e 's|/usr/bin/perl|${PERL}|' ${WRKSRC}/somescript

can be replaced by

SHEBANG_FILES=	somescript
SHEBANG_CMD=	${PERL}
