Well, I finally got it working. I found out my problem was that some stuff 
wasn't built. Check this post

http://code.google.com/p/iphone-dev/issues/detail?id=63

Also, for some reason, my llvm-svn directory wasn located where my LVMOBJDIR 
was, so that was another issue. 
Now I can compile using the XCode Tools.

Any chance you can provide more details on your fix ?? I have exactly the same 
error at this point, and have 
double checked (And rechecked).

All other stuff seem to build and install OK. I CAN'T see a configure script in 
the fixincludes directory which 
fixincludes/config.log implies is the issue, but can't seem to get it working.
Cheers
