Comment:

 The warnings from ghc-check are not causing the failure. The problem
 likely is that the version of hs-language-c is too old for the current GHC
 and needs to be updated.

 It should be as simple as
  - locating the Portfile (`port file hs-language-c`)
  - making a backup copy for later diff (`cp Portfile{,.orig}`)
  - modifying the version number at the end of the `haskell.setup` line and
 removing the `revision` line
  - running `sudo port -v checksum` in the directory (which will fail and
 print the correct checksums)
  - updating the checksums in the Portfile
  - running a test build (`sudo port -vt destroot`)
  - creating a patch (`diff -u Portfile{.orig,}`) and attaching it here

 Can you do that?
