I meant to mention this earlier - OSREL (referenced in the _xi-links:
target) is not defined.  So ports looking for arm-freebsd8.0-cc (for
instance) won't find it.


An earlier patch of yours had:

.if !defined(OSREL)
OSREL!= uname -r | sed -e 's/[-(].*//'
.endif

But the latest (and the one committed) does not.
