I am lost. Cabal-install says 'there is no available version of parsec that
satisfies ==3.1.1', but ghc-pkg says I have this parsec version installed.
mypkg$ cabal install --constraint=parsec==3.1.1
cabal: There is no available version of parsec that satisfies ==3.1.1
mypkg$ ghc-pkg list parsec
mypkg$ cabal --version
cabal-install version 0.8.2
using version 126.96.36.199 of the Cabal library
Maybe parsec is somehow installed incompletely?
'ghc-pkg check' shows no error.
