Aha, it looks like you got the sources from the HEAD rather than the
5.04 branch (which the recent 5.04.2 release was taken from).

To get the 5.04.2 sources, you do this:

	cvs checkout -r ghc-5-04-2 ...

to get the latest from the 5.04 branch, do this:

	cvs checkout -r ghc-5-04-branch ...

Without the -r option you get the HEAD, where indeed ForeignObj cannot
be passed to a foreign function and there are many other API changes
will no doubt will affect HOpenGL.
