I am seeing some strange failures of runghc on Linux/ppc (Fedora 11 specifically) with ghc-6.10.1 and ghc-6.10.2. For example "cabal install HTTP" works fine but "runghc Setup" failing to run. A workaround (other than using cabal-install) seems to be to compile Setup and then use the output of that to build the package. More strangely this only happens sometimes in the buildsystem, which makes me wonder if it is a fedora issue: most packages built ok in the fedora buildsystem except HTTP and haddock so far. http://koji.fedoraproject.org/koji/getfile?taskID=1319083&name=build.log http://koji.fedoraproject.org/koji/getfile?taskID=1320158&name=build.log On the other hand in a ppc box I tested on runghc seemed to fail consistently. ghci also segfaulted there. Anyway I thought I would ask here if anyone else had experienced something like this. Jens
