Greetings, I'm trying to recompile & reinstall the haskell platform 12.2.0.0. I have installed it successfully on a prior occasion but I decided to reinstall as I think I may have messed up my installed packages a bit while playing around with yesod. I intend to use cabal-dev or virtualenv for that in future. So I thought I'd do a clean install. I blew away my haskell platform and ghc, both of which were installed in a dir under my home dir. I also blew away my ~/.cabal/ dir. I then reinstalled by ghc 7.4.1 into ~/prg/haskell-platform-12.2.0.0. I then unpacked the sources of haskell-platform-12.2.0.0 and configured it with the prefix set to where ghc is. configure finished without error so I ran 'make'. It quits with what follows. How do I fix this?? With thanks, Jeff * Now do "make" followed by "make install" ************************************************** jeff@chunks:~/src/haskell-platform-2012.2.0.0$ make scripts/build.sh ************************************************** Scanning system for any installed Haskell Platform components...
