 Replying to [comment:14 simonmar]:
 > @markwright: will this work when the libraries are in the build tree, or
 only when installed?

 Only when they are installed (where it works great, I built 170 pkgs from
 hackage using in the Gentoo Haskell overlay with 7.7.20121102 using this
 patch with no LD_LIBRARY_PATH).

 In the build tree it can not find the libraries (of course a workaround
 would be to set LD_LIBRARY_PATH):

 {{{
 argus (ghclive) ghc-9999 $ env | grep LD_LIBRARY_PATH
 argus (ghclive) ghc-9999 $ find . -type f -name libHScontainers*.so -print
 ./libraries/containers/dist-
 install/build/libHScontainers-0.5.0.0-ghc7.7.20121102.so
 argus (ghclive) ghc-9999 $ ldd libraries/containers/dist-
 install/build/libHScontainers-0.5.0.0-ghc7.7.20121102.so
         linux-vdso.so.1 (0x00007fffae782000)
         libHSdeepseq-1.3.0.1-ghc7.7.20121102.so => not found
         libHSarray-0.4.0.1-ghc7.7.20121102.so => not found
         libHSbase-4.6.0.0-ghc7.7.20121102.so => not found
         libHSinteger-gmp-0.5.0.0-ghc7.7.20121102.so => not found
         libgmp.so.10 => /usr/lib64/libgmp.so.10 (0x00007f36da50e000)
         libHSghc-prim-0.3.0.0-ghc7.7.20121102.so => not found
         libc.so.6 => /lib64/libc.so.6 (0x00007f36da168000)
         /lib64/ld-linux-x86-64.so.2 (0x00007f36dab6e000)
 argus (ghclive) ghc-9999 $
