I recently upgraded my development platform to GHC 7.0.3 and the latest platform. After manually patching the cabal package for DrIFT (it had a dependency base<4 which was not satisfiable on my system, so I changed it to base-all) I tried to build jhc. Both version 0.7.7 fail to build, but there are different reasons:

I have not tried to use 7.03 yet. Good to know about the Type Families issue. Hmm.. that is strange. what version of DrIFT are you using? You should be using at least 2.2.3. http://repetae.net/computer/haskell/DrIFT/drop/

I used the cabalized version of DrIFT before, but installed your version now, to test whether it makes any difference. My installation of DrIFT is the most recent version. If you are interested, this is how I configured the program, curiously, the --with-hcflags flag is useless, so I patched the code by hand (at line 52 of "Makefile.am", I added "-XTypeFamilies" at the end): ./configure --prefix=$HOME/usr my Haskell toolchain is installed in $HOME/usr, because I don't want to destroy my system using experimental software. I guess, the problem is, that some of the core libraries changed their type-signatures. Yours, Robert Clausecker
