As far as I can see on my machine - cabal is /usr/bin/cabal - the apt package cabal-install is installed and lists /usr/bin/cabal as a file
So unless something really weird or magic-y happened, my cabal is debian's cabal.
And so -- my diagnosis -- the fact that cabal broke after an OS upgrade suggests that the apt package cabal has something wrong in its dependencies.
That sounds reasonable, but also means that your issue is not with Haskell but with Debian. In particular, it is Debian which does things like shifting from ghc's own private libgmp to its system one, thus introducing the possibility that a missed dependency can break things this way. (That said, make certain that you don't have a ~/.cabal/bin/cabal running around first --- if you mix distribution and cabal-install packages, you can easily get into this kind of mess. Which is why we recommend going with one or the other, and in particular not upgrading/replacing anything installed via the distribution except via the distribution.) -- brandon s allbery kf8nh sine nomine associates allbery.b@gmail.com ballbery@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net
