can't compile ghc-7.4.1: No rule to make target `libraries/process/ghc.mk'

I've rm -rf'd my ~/.cabal to ensure old stuff doesn't get in the way, installed all the dependencies (on fedora 17, bootstrapping with ghc-7.0.4), unpacked the ghc-7.4.1 tarball, and run: ./configure --prefix=`pwd`/installed && make && make install and here's the log: https://gist.github.com/20dd47cfac4c8bbe498c (sorry I missed the top, `tee` didn't work right and my scrollback buffer wasn't big enough. I think I got the important stuff though). there seems to be a lot of "*/*.hi is missing (ignoring)" messages, culminating in: Configuring hsc2hs-0.67... make[1]: *** No rule to make target `libraries/process/ghc.mk'. Stop. make: *** [all] Error 2 Any hints? Cheers, - Tim.
