I didn't see an answer jet so here it goes:
If you look closely you will see that HDBC-odbc-1.1.6.2 is installed but
module Database.HDBC.ODBC is not found (loaded). The problem lies in the capitalisation.
I ran into the same problem with missingH and the package filepath wich registers as filepath-1.0 while missingH.cabal is
looking for FilePath.
Hope that helps and gets attention by packege developers in the future.
Kind regards,
Andreas
