I already have a usable build -- the 6.6.1 binary release that  
Christian put together works fine on 10.5. My only goal here is to  
figure out why GHC doesn't build on 10.5, so that either 10.5 or GHC  
(depending) can get fixed.

The prior problem was not with gcc but rather with the system  
headers. I'm not aware of any problem between GHC and the gcc in 10.5  
at the moment.

I will try the build.mk options you suggest and report back.

Thanks,
Deborah
