In ghc 7.8.3 on the Mac, for some packages, cabal reinstalls the package instead of telling me I've already installed it. #2108

It's a known issue, Cabal doesn't track installed executables. See e.g. #227. |

I don't understand why my bug is either of the known issues I have been
As for the first, my problem is not with all executables, it is with some, a good package, e.g. hlint does not reinstall after a second cabal install Here's the output to show that: cabal install -j3 hlint bash-3.2$ cabal install -j3 hlint ghc-pkg list|fgrep hlint bash-3.2$ cabal install -j3 alex On Tue, Sep 16, 2014 at 4:04 PM, Miëtek Bak notifications@github.com

In ghc 7.8.3 on the Mac, for some packages cabal reinstalls the package instead of telling me I've already installed it. ghc-pkg check shows I have no issues, e.g.:
bash-3.2$ cabal install cabal-install

bash-3.2$ ghc-pkg check
bash-3.2$
Other packages that have this problem include alex, and an example of a package that doesn't have this problem is vector. Should I file a bug?
