[HOpenGL] Compiling HOpenGL under recent versions of GHC

[jss at au.mensa.org]

Oh, 

one extra tip, now for any Gentoo user trying to build the GHC CVS :

For some reason the bootstrap/build process for GHC CVS would not 
build the the alex within the build tree first, and then use that for the 
rest of the build, 

But, there is an ebuild for a recent version of alex. So there is no real 
hassle at all for Gentoo users.  The ebuild is masked, with ~x86, but 
therefore does build fine at least on x86 systems (including AMD 32 bit).

so just run:
ACCEPT_KEYWORDS="~x86" emerge alex

and then build your GHC CVS.

cheers,

John
