Hi all,
I'm trying to get a program that uses the Data.Generics module to compile under the head version of GHC, but I am having trouble getting the syb package installed.
I believe I am using the most recent version of cabal:
> kfisher-laptop:/Users/kfisher/pads/dirpads/language-c-quote>~/.cabal/bin/cabal --version
> cabal-install version 0.8.0
> using version 1.8.0.1 of the Cabal library
When I ask cabal to install the syb package, I get the following error:
> kfisher-laptop:/Users/kfisher/pads/dirpads/language-c-quote>~/.cabal/bin/cabal install -w ~/sw/ghc-head/bin/ghc
> Resolving dependencies...
> Downloading mtl-1.1.0.2...
> Configuring mtl-1.1.0.2...
> Preprocessing library mtl-1.1.0.2...

> Registering syb-0.1.0.3...
> cabal: ghc-pkg: <stdin>: hGetContents: invalid argument (invalid UTF-8 byte

> language-c-quote-0.1 depends on syb-0.1.0.3 which failed to install.
> syb-0.1.0.3 failed during the building phase. The exception was:

The full trace is included below.
Here's the version information for the ghc I am running.
> Kfisher-laptop:/Users/kfisher/pads/dirpads/language-c-quote>~/sw/ghc-head/bin/ghc --version
> The Glorious Glasgow Haskell Compilation System, version 6.13.20100210
The cabal website suggests sending questions to this list...
Any suggestions for how to fix this problem?
