Are you using the Fedora system installation of GHC by any chance? If so, the problem is that Fedora doesn't include GHC-as-a-library by default. See [1] for more details and how to resolve it.

If you're *not* on Fedora, please provide more information on your OS and how you install GHC/Haskell Platform.

Hello People!

I've been trying to get Yesod going!

Updated cabal (as instructed).
Installed the yesod-platform package.

Next step, would be to install the yesod-bin package (for the yesod executable, server and stuff...)! But when I try:

./cabal install --dry-run yesod-bin

I get these messages:

Resolving dependencies...
cabal: Could not resolve dependencies:
trying: yesod-bin-1.2.7.3 (user goal)
next goal: ghc (dependency of yesod-bin-1.2.7.3)
Dependency tree exhaustively searched.

I'm gonna get into trouble again, right?

Can anyone tell me what to do next?

Thank you very much!

Gilberto
