Hello, Could this be a global/user install issue? That is, if the old-time package is installed per-user, and you're trying to install a package globally, the user-installed packages all show up as hidden, because they can't be dependencies of a global install. This shows up frequently because global installs are the default when doing "runghc Setup.hs install", but per-user installs are the default for cabal install. If you use both of these commands, you'll run into this sooner or later. You can run "ghc-pkg list" to get a listing of what's installed where. If "old-time" is only in the local database, you should reinstall it into the global database (or install everything globally). Cheers, John

Database/HaskellDB/HSQL.hs:25:7: Could not find module `System.Time': it is a member of the hidden package `old-time-1.0.0.3' it is a member of the hidden package `old-time-1.0.0.2' Use -v to see a list of the files searched for.
old-time-1.0.0.2 is installed (via cabal).
Suggestions on how to fix this or which haskell db (for sqlite3) package will actually install greatly appreciated.
I get a lot of failures in hackages which involve that dreaded "hidden package" message. Anybody care to enlighten us mere mortals as to why it seems to occur so frequently (at least for me).
