Sorry, the version numbers 1.2.3 and 12.3.4_5 were chosen as examples,
not meant to be taken literally.

This will cause disaster.  If you do this to rebuild foobar, poudriere
will also update perl.  Then, when you install the fixed foobar, pkg
will intall the updated perl.  Then the unrelated package bazqux you
didn't rebuild but which also depends on perl and isn't compatible
with the new version silently breaks.  And the first you will hear
about it is when all the bazqux users from the third floor show up at
the door to your office with torches and pitchforks.

What we are looking to do is rebuild only foobar and the things that
depend on foobar, NOT the things that foobar depends on.

Thanks!
