 Building ekmett's lens package from HEAD (revision 80c1fddf) with the
 following error fragment:

 }}}

 Full log is attached. I'm not trying to build with shared libraries, or
 profiling, or anything like that.

 I can reproduce this failure starting from a fresh Debian testing install
 as follows:

 1. Bootstrap GHC HEAD.
 {{{
 sudo aptitude install ghc=7.6.3-6 happy=1.19.0-1 alex=3.1.0-1
 sudo apt-get build-dep ghc
 cd /var/tmp
 git clone git://git.haskell.org/ghc.git
 cd ghc
 git checkout e01367ff
 ./sync-all get
 ./boot
 ./configure
 # Adjust the -j option to taste.
 make -j4
 sudo make install
 }}}

 2. Bootstrap cabal-install.
 {{{
 cd /var/tmp
 wget http://www.haskell.org/cabal/release/cabal-install-1.18.0.2/cabal-
 install-1.18.0.2.tar.gz -O - | tar xzf -
 cd cabal-install-1.18.0.2
 patch -p3 < cabal-install-ghc-HEAD.patch # see attached
 sudo aptitude install zlib1g-dev
 ./bootstrap.sh
 export PATH=$HOME/.cabal/bin:$PATH
 cabal update
 }}}

 3. Build lens.
 {{{
 cd /var/tmp
 git clone https://github.com/ekmett/lens
 cd lens
 git checkout 80c1fddf
 cabal install cpphs
 cabal install # this fails
 }}}

 Using gcc Debian 4.8.2-14, ld 2.24. The GHC fingerprint and output of `ghc
 --info` is attached.
