I tried to build the newest haskell-platform-2011.2.01 from source on Ubuntu 11.04, following the instructions http://www.vex.net/~trebla/haskell/haskell-platform.xhtml. But there was still an configure error. $ ./configure ************************************************** * * Haskell Platform Source Installer * * For the Haskell Platform 2011.2.0.1 and GHC 7.0.3 * ************************************************** checking build system type... i686-pc-linux-gnu checking host system type... i686-pc-linux-gnu checking target system type... i686-pc-linux-gnu checking for ghc... /usr/local/bin/ghc checking for ghc-pkg... /usr/local/bin/ghc-pkg checking for hsc2hs... /usr/local/bin/hsc2hs checking version of ghc... 7.0.3 checking version of ghc-pkg matches... yes checking ghc actually works...

The following are the libraries I already installed sudo apt-get install libgl1-mesa-dev sudo apt-get install libglc-dev sudo apt-get install freeglut3-dev sudo apt-get install libedit-dev sudo apt-get install libglw1-mesa libglw1-mesa-dev Can anyone suggest the libraries my OS missing ?
