I've pushed a new tarball based on 9c48d8a02dd80bba3bd313bc52add841530e28dc. I have pushed essentially everything into this candidate that I expect will go into 8.0.1. It validates but it isn't nearly as well tested as the previous tree. I'll try doing some further builds tomorrow and let you all know if anything goes awry.

From running `./configure` on

http://downloads.haskell.org/~ghc/8.0.1-rc3/ghc-8.0.0.20160408-x86_64-unknow...

This binary distribution was uploaded unintentionally and was built for general public consumption. Our binary distributions won't be built with libdw support

it seems that the required version of elfutils is 0.158, however this version of elfutils is not checked when running `./configure` on

http://downloads.haskell.org/~ghc/8.0.1-rc3/ghc-8.0.0.20160411-src.tar.xz

That is, instead of get an error on configuration time because my version of elfutils is too old, I get an error on compilation time.

Ahhh, yes, it seems like neither the source nor binary distribution configure scripts actually check for the libdw version. Thanks for noticing this! I've opened #11820 to track this and D2103 with what I believe is a fix. Cheers, - Ben
