Just a small additional piece of information.
Nowadays many ports claim
Warning: All compilers are either blacklisted or unavailable;
defaulting to first fallback option
but do install nevertheless at the end. I would say that this is a bug
in either the portfiles or portgroups that's worth fixing anyway, but
I just wanted to say that if you make this an error, suddenly a huge
number of ports that can easily be built will simply stop working.
One of annoying things is that I'm getting this warning when I run
"port livecheck maintainer:..." and I have absolutely no clue where it
