Comment(by maeder):

 I've tried now the same with ghc-7.6.0.20120815 under x86_64 linux and I
 got the same failure.
 Unfortunately I could not use a binary snapshot

 {{{
 maeder at pollux:/local/home/maeder/ghc-7.6.0.20120815> ./configure
 checking for path to top of build tree... utils/ghc-pwd/dist-
 install/build/tmp/ghc-pwd: /lib64/libc.so.6: version `GLIBC_2.14' not

 configure: error: cannot determine current directory
 }}}

 I'll try out
 http://www.haskell.org/ghc/dist/current/dist/ghc-7.7.20120820-src.tar.bz2

 (Also the network package is now updated on hackage, so no patches are
 needed anymore)
