The file length is correct.

If ghc worked in the past on your machine, then your Xcode version  
should be fine.  (It's really only important that we have a version of  
gcc that plays nicely with ghc.)  But you are right, I need to update  
that readme for Tiger (the recommendation for 3.0 really only applies  
to Leopard.)

I had a closer look at cross compilation for 10.4 and I think I know  
why we get the bus error and how to avoid it.  To avoid you having to  
download another GHC build, which may have problems again, I have  
compiled two versions of hello world and put them in a tar ball at

http://www.cse.unsw.edu.au/~chak/HelloWorld.tar.bz2

It contains HelloWorld-Leopard and HelloWorld-Tiger.  Please try to  
run them both.  I believe HelloWorld-Leopard will also give you a bus  
error, but I hope HelloWorld-Tiger will work.

(Interestingly HelloWorld-Tiger is about 8x bigger than HelloWorld- 
Leopard.  I don't think this has anything to do with GHC, but is due  
to Apple's cross-compilation SDK.)
