 Replying to [comment:43 parcs]:
 > I haven't tested `cabal` with my branch but I don't think my changes are
 causing the errors you're experiencing. I'm willing to bet that it's due
 to recent changes pushed to master. (Or maybe you forgot to do `git
 submodule update` after checking out my branch?)

 I'm pretty sure I updated the submodules, but I'll do a fresh build to
 double check.  Except for the excessive system-time the parallel make
 actually works for me, as long as I don't do `cabal -j`.  I can even
 install packages with parallel GHC / non-parallel cabal.

 Could I get a fix on what other people who are testing this branch are
 seeing?  Are you able to install packages with `cabal -j`?
