GHC 7.0.3 produces corrupt .hi files for qtHaskell

I installed qtHaskell 1.1.4 by installing Qt 4.7.3 through brew. I ran ./build --enable-shared for qtHaskell, which failed after compiling and installing all of the C bindings. I then ran cabal install --disable-library-for-ghci, per http://hackage.haskell.org/trac/hackage/ticket/791 .

I can successfully build, but I get the following warnings:

[1 of 1] Compiling Main             ( Main.hs, dist/build/qtTest/qtTest-tmp/Main.o )

When I run the compiled program, labels do not show up properly, and I'm pretty sure that it's due to these issues.
