Is your source tree fully up to date? This was fixed recently, I think.

I think this was the patch

  * Fix nasty Simplifier scoping bug

Pls close if that's all it was.

And if it is still broken for you, can you please attach the source code you were trying to compile and tell us what the commandline was?

[megacz]

Sorry about the slow reply.

I've tried updating GHC to latest darcs, but now the NDP build fails at an earlier point ("cabal-bin: cabal: Don't know what to do!... Warning: Package is unbuildable"), so I can't tell if it helped or not.

So, I guess, close this bug since it can no longer be reproduced. Thanks for your time!

Ian and Roman are working on fixing the build-system problem.
