internal error with ghc 6.4.1

Hello,

I got the following error while compiling gtk2hs:

ghc-6.4.1: internal error: evacuate: strange closure type 26222
   Please report this as a bug to glasgow-haskell-bugs@xxxxxxxxxxx,
   or http://www.sourceforge.net/projects/ghc/

I make an image of the directory where this occured and saved it, in 
case it might be of any use.

I also saved a transcript of the output of the build.

If either of these might be helpful, send me an email and I will send 
you the files.

The tar file (already compressed) has size 10254848.  If you want to see 
the file and this is too large for an email attachment, let me know 
where to upload it, or if necessary I can put it on a server for you to 
upload.
