You can also just download  and install the binaries for your platform at http://leksah.org/download.html.

That sounds nice, so I thought I'd try out leksah again.

Unfortunately, the dependencies rule out GHC-7 (base < 4.3, Cabal < 1.9,
containers < 0.4 were the ones that sprang to the eyes immediately).
Bummer

Maybe someone could try relaxing the bounds and build it with GHC-7, and -
if it works - upload a new version?
(I could try if I get a go-ahead from Hamish or Jürgen)
