I'm getting this for test linker_unload on Linux. I'm sure it's not my fault!
But it makes validate fail

I've tried this in an Ubuntu 12.04.5 LTS/x86_64 environment, but couldn't reproduce it. I'm quite confident that '__gmpn_rshift' is in fact not missing, otherwise you'd get much more failures (and GHC probably wouldn't even build). I also don't think that Ubuntu 12.04's is too old, as it's a GMP 5.0.2 version afaik. Does `TEST=linker_unload` fail deterministically? Would it be possible to update your `sudo apt-get update` & `sudo apt-get dist-upgrade` your Linux environment with the latest bugfixes to Ubuntu 12.04.5? That way we can be sure it's not a subtle bug already fixed upstream... Finally, if that also doesn't help, can you try cloning a fresh tree via git clone --recursive git://ghc.haskell.org/ghc.git <new-folder-name> and invoke ./validate inside <new-folder-name>? HTH, hvr
