Hi all,

Prolog: I have installed GHC v7.6.3, from source, on Ubuntu 13.0.4.

I think I've made my GHC v7.6.3 installation unstable, because I'm having lots of trouble with "ExitFailure 139"s when cabal installing. And I'm wondering if this is a pertinent clue:

dbanas@dbanas-lap:~/prj/plush$ cabal unpack lifted-base
Unpacking to lifted-base-0.2.1.0/

dbanas@dbanas-lap:~/prj/plush$ pushd lifted-base-0.2.1.0/
~/prj/plush/lifted-base-0.2.1.0 ~/prj/plush ~

dbanas@dbanas-lap:~/prj/plush/lifted-base-0.2.1.0$ ghc --make Setup.hs

Setup.hs: At least the following dependencies are missing:

monad-control ==0.3.*,

transformers-base ==0.4.*
dbanas@dbanas-lap:~/prj/plush/lifted-base-0.2.1.0$

What I'm attempting to call attention too, with the above excerpt, is this:

If I compile and run "Setup configure" I get a core dump, but if I just run "Setup.hs configure" (taking advantage of the fact that Setup.hs begins with a shebang line) it works fine.

Is this a clue as to how I've horked up my ghc installation?

Thanks!
