Package version question with Cabal

Oops, this should be "cabal install hsshellscript-3.3.3", not just "cabal 
install":

~/src/hsshellscript $ cabal install hsshellscript-3.3.3
Resolving dependencies...
All the requested packages are already installed:
hsshellscript-3.3.3
Use --reinstall if you want to reinstall anyway.

But when I try "--reinstall", I get this error:

~/src/hsshellscript $ cabal --reinstall install hsshellscript-3.3.3
Resolving dependencies...
cabal: Could not resolve dependencies:
next goal: hsshellscript (user goal)
rejecting: hsshellscript-3.3.2, 3.3.1, 3.3.0, 3.2.0, 3.1.0 (global constraint
requires ==3.3.3)
Dependency tree exhaustively searched.

What does this mean...?

I've also in vain searched for a way to remove a cabal installed package.

Thanks,
Volker
