Comment (by RyanGlScott):

 Case in point for why build logs are critical here: I just tried running
 the test suites for `stm-delay-0.1.1.1` using commit
 3cfb12d8adac37e5565d66fd173e4648cc041e65 using a standard:

 {{{
 $ cabal configure -w ~/Software/ghc/inplace/bin/ghc-stage2 --enable-tests
 $ cabal test
 }}}

 And both test suites successfully built and ran for me. So clearly
 `stackage-head` is doing something different, but I have no idea what that
 could be.
