On Mac OS X 10.4, I can't link programs that use readline unless I explicitly specify the GNUreadline framework on the ghc command line... Note that this happens for programs that explicitly use System.Console.Readline, not in general ghc use.

The readline package spec should include the framework option (if not, its a bug in the config of the readline package IMO).

I agree; the framework is supposed to be linked in automatically. Yitzchak, what version of GHC are you running? Is it a development build or a release?
The release version 6.6.1, via the (former) standard download link on the GHC web site.
Also, what is the output of the following commands?
$ ghc-pkg describe readline name: readline version: 1.0
Ah, OK. The readline package was changed in 6.8 to link with the framework automatically (it did not in 6.6.2 and earlier). If you don't want to update ghc, you can just download version 1.0.1 of readline from hackage and install it manually: http://hackage.haskell.org/cgi-bin/hackage-scripts/package/readline-1.0.1.0 Hope that helps, -Judah
