I’m afraid I cannot reproduce this.  I removed the successfully built
ghc-resourcet from the store and rebuilt it successfully.

There are a bunch of warnings, but I end up with a successful build of
/gnu/store/y8rp418ynjb57hv824b7apih5bmpibba-ghc-resourcet-  Thoughout 
the build it mentions
/gnu/store/ngqrlni2iqs8lfbbjf1bd55bymc689d3-ghc-resourcet- as the output 
directory, which
matches the build log on hydra.

My local log looks rather different (see attached file).

For one, I don’t see these messages:

--8<---------------cut here---------------start------------->8---
Configuring resourcet-
Warning: This package indirectly depends on multiple versions of the same
package. This is highly likely to cause a compile failure.
package transformers-compat- requires transformers-
package transformers-base-0.4.4 requires transformers-
package primitive- requires transformers-
package monad-control- requires transformers-
package hspec-core-2.2.4 requires transformers-
package hspec-2.2.4 requires transformers-
package QuickCheck-2.10.1 requires transformers-
package resourcet- requires transformers-
package mtl-2.2.1 requires transformers-
package mmorph-1.0.6 requires transformers-
package exceptions-0.8.3 requires transformers-
--8<---------------cut here---------------end--------------->8---

Nor do I see this message:

    ghc-pkg: unable to decommit memory: Invalid argument

I don’t know what this message means, but the messages about requiring a
different version of the transformers package probably describe the
problem on Hydra.  For some reason the build environment I have on my
machine is not the same as that on Hydra.  I guess that this is related
to ghc-pkg failing to set up the environment.
