[Nix-dev] GHC 7.8.2-binary.nix to bootstrap GHC HEAD

[Corey O'Connor]

Hi Mateusz,
Did you make any progress with this?
I set up a Nix build of the GHC 7.8.3 branch to bisect some bugs. I think I
ran across a similar problem: An installed GHC will search for some files
in the directory specified by the release version and other files in the
version dynamically determined at compile time.

I resolved this locally with the patch:

diff --git a/configure.ac b/configure.ac
index 8c013f8..d6477d4 100644
--- a/configure.ac
+++ b/configure.ac

-: ${RELEASE=YES}

 # The primary version (e.g. 7.5, 7.4.1) is set in the AC_INIT line
 # above.  If this is not a released version, then we will append the
