Yes, that's the way it currently is in the ports tree.

This is exactly the problem I want to solve with cabal.port.mk. You
can try to look at
https://marc.info/?l=openbsd-ports&m=160858285410366&w=2
A quick search in the archives will show the justification and the
history of the effort.

The current state of the work is I'm waiting on cabal 3.4 official
release gated by ghc-9.0. I'm also looking for people needing this work
and your attempt to add git-annex gives me more motivation to finish.

BTW, trying to build with cabal also needs devel/libmagic port, or else:

cabal: Missing dependency on a foreign library:
* Missing (or bad) C library: magic

Thanks
