To be precise, I ran the following and can use --disable-profiling with ghc-7.6.3 now.

I spoke too early.

Weird problem, running `cabal install --disable-profiling -j1` works, but using a higher number of cores I get the same error during cabal configure. Here is what I did.

$ ghc -V

The Glorious Glasgow Haskell Compilation System, version 7.6.3

$ cabal -V

cabal-install version 1.22.0.0

using version 1.22.0.0 of the Cabal library

$ cabal install -j3 --disable-profiling mtl

cabal: Error: some packages failed to install:

mtl-2.2.1 depends on transformers-0.4.2.0 which failed to install.

transformers-0.4.2.0 failed during the configure step. The exception was:

ExitFailure 1

$ cabal install -j1 --disable-profiling mtl

(This works fine.)

Am I missing something?
