7315	Link error while compiling executables	bgamari		"
On GHC master (ef786b6cbc5f67a673bf8c10be5311317c1e7b88) attempting to build any executable results in a linker error. For instance, `cabal install cmdargs` results in,
{{{
     [37 of 37] Compiling Main             ( Main.hs, dist/build/cmdargs/cmdargs-tmp/Main.o )

     /usr/bin/ld: cannot find -lHStransformers-0.3.0.0-ghc7.7.20121009
     collect2: error: ld returned 1 exit status
     cabal: Error: some packages failed to install:
     cmdargs-0.10 failed during the building phase. The exception was:
     ExitFailure 1
}}}
Yet transformers appears to be installed (although the version suffix doesn't appear to match),
{{{
