exactly. The package names like libghc6-ghc-prof-6.12.1-df3ea represent a cabal package with a certain ABI hash (in this case starting with df3ea). If these don’t match, the packages are broken, therefore we encoded it in Provides/Depends. A recent upload of ghc6 seems to have changed the ABI hash of the "ghc" package (which is rather internal and only used by compiler-close stuff). Therefore, libghc6-ghc-mtl-prof is uninstallable. A nmu of haskell-ghc-mtl will create a package which depends on the changed ABI, have an uploaded Provides and thus clear the BD-Uninstallable issue.
