[Haskell-cafe] pcre-light install fails with undefined reference to _impure_ptr

[Patrick Caldon]

Not seen this one before.

I'm trying to install pcre-light with WinXP 64, Cygwin 1.7.1, Cabal 
0.8.0, and ghc 6.12.1. Trying to reinstall "base" with cabal fails as 
well with an internal error (see below), but I'm assuming that's 
quasi-intentional/unsupported feature or something.

Any ideas?  My ultimate goal is to install ghc-core to help track down 
some performance problems I'm having.

Thanks,
Patrick.
