Perhaps it's better to solve this in HTTP itself? It gives decent
error messages in other cases:

$ export HTTP_PROXY=foo
$ cabal update
Downloading the latest package list from hackage.haskell.org
cabal: openTCPConnection: host lookup failure for "foo"

$ export HTTP_PROXY=http://localhost:3128
$ cabal update
Downloading the latest package list from hackage.haskell.org
cabal: does not exist
