[Haskell-beginners] installing cabal 1.20 on linux mint debian edition (LMDE)

[Christopher Allen]

Not to judo past the original question, but would it solve your problem to
use an Ubuntu PPA[1]or the cabal binary distribution[2]?

Also were you trying to build it in a sandbox? You shouldn't be installing
things willy-nilly outside of a sandbox[3].
