Re: Link errors when using the GHC API

I'm running Gentoo Linux (x86). I emerged the latest GHC (6.6). So GHC is 
built from source.

$ uname -a

$ gcc --version
gcc (GCC) 4.1.1 (Gentoo 4.1.1)

$ ghc --version

$ ghc-pkg list

rts-1.0, stm-2.0, template-haskell-2.0, unix-1.0

BTW, why is the (ghc-6.6) package listed between parentheses?

I also emerged GHC on another PC with the same architecture running the same 
Gentoo version and there I had the same error:

 Seems like something didn't build right...  You might use 'nm' to
 examine your libHSCabal.a to see if a similarly named symbol is
 present.  For example, is there a leading underscore?  May the
 version (m1zi1zi6) isn't present?

When I 'nm /usr/lib/ghc-6.6/libHSCabal.a' and search for, for example, 
Cabalzm1zi1zi6_DistributionziPackage_a_closure I see that it is indeed an 
(U)ndefined symbol. I don't know what that means though.

Reemerging GHC or Cabal also doesn't help.

Any help is highly appreciated.

Greetings,

Bas van Dijk.

Yeah. That'd have a different quick fix:

cp /usr/lib/ghc-6.6/libHSCabal.a /usr/lib/Cabal-1.1.6/ghc-6.6/

because ghci uses the .o files and ghc uses the .a ones.

I updated the x86_64 dist yesterday, and I'm in the process of uploading a new
