[Haskell-cafe] A Cabal problem

[Mario Blazevic]

	I have a problem with Cabal: it doesn't seem to pick up the "Main-is:" 
option from the configuration file.

Here's my "scc.cabal" file. Note the "Main-is:" line:

	And below are the outputs of Cabal configure and build commands. Note 
the absence of "--main-is" ghc command-line option. I'm doing this on 
Ubuntu 8.04 Linux, but I get the same problem with Gentoo. Is there
something wrong with my configuration file, or is this a bug in Cabal?
