Right, but if all ghcs always use /usr/include/ghc then you can only run the ghc that is the `current alternative' -- if you try to run the other one, it will find the wrong libraries (which may or may not work). So, without root intervention to change the current alternative, you could still only run one, which makes having multiple versions installed a lot less useful. And, even if ghc itself did not use /usr/include/ghc, your multilingual makefile would get the wrong includes if you used the non-current-alternative ghc. -- Mieszko _______________________________________________ Glasgow-haskell-users mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
