LHC (as of September 19) doesn't build with the latest Cabal.
$ runhaskell Setup build Preprocessing executables for lhc-0.9... Building lhc-0.9... <lines omitted> [2 of 2] Compiling Main ( lhc-pkg/Main.hs, dist/build/lhc-pkg/lhc-pkg-tmp/Main.o ) lhc-pkg/Main.hs:612:36: Not in scope: `package' lhc-pkg/Main.hs:612:50: Not in scope: `package' lhc-pkg/Main.hs:626:30: Not in scope: `package' <etc. About 20 similar errors total>
Simply replacing 'package' with 'sourcePackageId' doesn't work: Cabal seems to have changed package dependency handing a bit:
