 git-annex has been a great way for me to explore both Haskell and software packaging.
 
 I enjoyed the interview on LWN.

+"cabal: not found"
+
+Since cabal-install is a build-dependency of the package, why is cabal not
+available?
+
+The debian package builds just fine here. I diagnose that the problem is on
+your build system.
+
+All your patch is doing is modifying it to not build the package using
+cabal. But, debian/cabal-wrapper's comments explain why we need to use
+cabal.
