 `port install git-annex` fails for me (I never installed it before, so I
 cannot give any details on changes between versions or so) on Big Sur
 11.6.2.

 The compile error seems to refer to some Haskell module `Network.BSD` that
 no longer supports the `getProtocolNumber` used by git-annex:
 {{{

 }}}
 I got a few hits for the same error message, often on ARM architectures,
 but no related discussion or bug reports.  I am also not familiar with
 Haskell.
