I have been toying with this exact problem. I see only a couple of ports
Makefiles are attempting to deal with this. There is no exact current
best practice, but I personally like the way Tobez does this in
net/p5-NetAddr-IP:
.if !defined(BATCH)
pre-fetch:
@${PERL} -M5.6.0 -e '' >/dev/null 2>&1 || \
( ${ECHO_CMD} "This port requires perl 5.6.0" ; exit 1 )
.endif
This gives instant feedback, and also allows finer granularity (e.g.
perl >= 5.6.1)
