[Haskell-cafe] GHC-8.6.3 question.

Dear colleagues I'm in the process of having to reinstall ghc-8.6.3 in order to use a library (gtk) where the last successful build is 8.6.3. I was able to do that on linux. However I'm now trying to repeat this under OSX. I couldn't find a binary version, so I've been trying to build from source- but i'm hitting an issue on 'make install': stage2/build/libHSghc-8.6.3_p.a: copyFile: does not exist (No such file or directory) I'm not seeing a stage2 directory in my build area, but I'm not seeing any earlier error messages so I'm unclear why the build is failing. If someone familiar with this release and/or th build process could suggest any causes or fixes that would be helpful. thanks, David Duke
