 on commit 716f3586e23faeb8a4a08e77ebdbfa645c15f9a8 of my in progress
 project git at github.com:wellposed/numerical-core.git , when i try test
 library coverage by the following command  (asuming dependencies are
 installed)

 cabal clean ; cabal configure --enable-tests --enable-library-coverage;
 cabal build; cabal test

 i get the following output at the end

 Writing: numerical-core-0.1.0.0/Numerical.Nat.hs.html
 hpc: can not find numerical-core-0.1.0.0/Numerical.Array.Shape in
 ["./.hpc","./dist/hpc/mix/numerical-core-0.1.0.0","./dist/hpc/mix/spec-
 suite"]

 this apparently only happens on OS X.

 here are the build logs from my run
 https://gist.github.com/cartazio/11312249
 (i'll amend that to link to a cleaner output later)
