I installed ghc 6.6 from source ok. But then when I tried installing it with the "extralibs" to get all the functionality that had been unbundled in 6.6, I hit a glitch.

Anyone ever seen anything like this?

In case it matters, this is ssh-ed in to a virtualized user mode linux session.

I'm guessing what happened is that during the install the build system decided to rebuild ghc-pkg (I'm not sure why), but by that time you had already installed the new compiler, and the previous interface files weren't compatible with the new compiler. (I don't know why that would be the case either, since both compilers are 6.6...). You might be able to work around it by $ (cd compat && make clean && make UseStage1=YES) $ (cd utils && make clean && make UseStage1=YES) Cheers, Simon
