Compile failure with GHC 7.4 #301
Description
I guess some variant of Murphy's law applies: Travis script didn't test with GHC 7.4 and so the lower bound on containers wasn't validated (GHC 7.4.2 bundles containers-0.4.2.1):
Configuring component lib from distributed-process-0.6.6

Use -v to see a list of the files searched for.
In any case, the lower bound should be containers >= 0.5. However, there is not going to be any install-plan for GHC 7.4.2 w/ that constraint (so I'd suggest also setting base >= 4.6 to declare support for GHC 7.6/base-4.6 or later only)

After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: distributed-process (50), containers
(27)
