GHC 6.8.1 on Mac OS 10.5 Leopard (Intel) - Configure fails

Hi, I know this issue has been discussed on the list before, but I have not found a solution in the archives. Running ./configure on Mac OS 10.5 (Intel) is aborted with this error message: checking build system type... i386-apple-darwin9.1.0 checking host system type... i386-apple-darwin9.1.0 checking target system type... i386-apple-darwin9.1.0 Which we'll further canonicalise into: i386-apple-darwin checking for path to top of build tree... dyld: Library not loaded: GMP.framework/Versions/A/GMP Referenced from: /Users/Carsten/Desktop/ghc-6.8.1/utils/pwd/pwd Reason: image not found configure: error: cannot determine current directory Any ideas how to get around this issue? Thanks, Carsten
