ubuntu - Failed to install ssh-0.2.12 (haskell package ) -


i tried install haskell package ssh-0.2.12 sudo cabal install ssh-0.2.12 returns src/ssh.hs:58:114: not in scope: type constructor or class `sha1'

src/ssh.hs:59:115: not in scope: type constructor or class `md5' failed install ssh-0.2.12 cabal: error: packages failed install: ssh-0.2.12 failed during building phase. exception was:

i on ubuntu 13.04. help.

this because ssh depends on cryptohash without uppper version bound.

it written against cryptohash 0.9.1, in md5 constructor existed , marked deprecated, cryptohash 0.10.0 out doesn't contain anymore.

your cabal install latest versions of dependencies if there no restrictions on them.

the right thing file bug against ssh package gets updated. can find bugtracker url on hackage page.

note: controversial whether upper version bounds or bad.
