Find Universal?

"base port" is not a term I'm familiar with, but you can show which ports have been installed with the universal variant using:

port -q installed | grep +universal

I think that there are actually few, if any ports, that I have currently installed that need to be universal, but a while back I had a port or two that needed to be (ie wine).  And, then all the dependents ended up being universal.  Is there any way to figure out if any of my manually installed ports default to universal?

I suppose you could grep their Portfiles to see if they say "default_variants +universal".

port file requested | sort -u | xargs grep -E 'default_variants[[:space:]]+\+universal'

Not easily. I may have posted a long complicated command line to do that on this mailing list some years ago. 

It would be easy to reinstall *all* active ports to remove the universal variant, with something like:

sudo port upgrade --enforce-variants active -universal

But if any other port required any of those ports to be universal, that would break that other port. You could of course do this and then just see what breaks.

They may be installed universal on your system, but that is not their default installation mode, and there is no inherent reason why either of them need to be installed universal, unless of course it is required by another port that depends on them. Neither of those ports' Portfiles even contains the word "universal".

That last category can be reinstall, but would have to be done in the right order, I think?

By grepping Portfiles, I count only 10 ports in our collection that default to the universal variant. That number may be slightly off, but it is a very rare occurrence.

Ports that are not 64-bit compatible, and that therefore only install 32-bit, and that therefore require their dependencies to be installed universal, are probably more common. You could show those ports that are installed for 32-bit only by using:

port -vq installed | grep "archs='i386'"
