[Fedora-haskell] x86_64 packages

Hi, I am running FC3/x86_64. When I install the ghc(64)-6.4-7.x86_64 packages, ghc runs fine in batch mode, but ghci fails to work with the following message: $ ghci ghc-6.4: not built for interactive use On the other hand, when I install the i386 packages, ghci works fine but ghc compilation fails at the assemby step: [jcheney@dhcp-2-148]$ ghc Main.hs -o main /tmp/ghc4976.s: Assembler messages: /tmp/ghc4976.s:67: Error: suffix or operands invalid for `push' /tmp/ghc4976.s:119: Error: suffix or operands invalid for `push' /tmp/ghc4976.s:163: Error: suffix or operands invalid for `push' [etc...] Is this a known issue? I'll try building from the source to see what happens. Thanks, --James
