[Haskell-cafe] building the unix package and cabal

Hello, I have been trying to build the unix package on RedHat RHEL 5. Over the weekend I read through the Cabal documentation. The unix-2.2.0.0 unix.cabal specifies the "build-type" attribute as "Configure". Based on Cabal doc, I should run ./configure. After this step then what? Bottom line is how do I build the unix-2.2.0.0 package on RHEL 5? Thank you, Vasili
