Hello, when trying to use wxhaskell on ghc-6.2.2 on an amd64 (unregistered gentoo build) the following happend: $ ./a.out a.out: internal error: adjustor creation not supported on this platform Please report this as a bug to glasgow-haskell-bugs@haskell.org, or http://www.sourceforge.net/projects/ghc/ I'm not sure if this is a bug because amd64 is not officially supported.
