I haven't tried. The old GHC-6.10.4 version doesn't use llvm.

That's right. There's a fairly old document that explains it:

The new version should definitely before the end of February, and 
hopefully sooner. In the meantime, this info from a previous post may be 
helpful:

William,

1. Take the patches from here...

http://projects.haskell.org/ghc-iphone/downloads/patch.snowleopard/

2. Read the README.SnowLeopard file.

3. Then install according to the instructions in GHC-iPhone.pdf (which
is a little old), except that you use ghc version 6.10.4 in all cases.

config-iphone.sh is created by applying the patches.
