Comment (by Nolari):
Thanks! Editing the cabal file indeed works. By the way, which branch of
GHC should I be using with NDP? I'm trying both the
http://darcs.haskell.org/ghc/ and http://darcs.haskell.org/ghc-2008-06-02/
branches.
The `ghc-2008-06-02` one doesn't seem to understand the `-fno-ds-multi-
tyvar` option, and `-dcore-lint` gives no additional output. Here's the
result of my last 3 `make rebuild.library.ndp` runs:
{{{

On the `ghc` branch the option `-fno-ds-multi-tyvar` is understood, and
gives me the following on `make rebuild.library.ndp`:
