Why is ghc-pkg looking only at globally-installed packages?
It's not ghc-pkg, it's Cabal that by default only looks at the global packages. You can configure with --user to have it look at the user ones. Personally I'm in favour of switching the default to --user.
Of course it cannot use user packages and then install globally, and the current default prefix is /usr/local which is usually root only, so if we switch the default to user installs then we'd have to switch the default prefix. I'd prefer that too though. However it's a change that would require general consensus.
Ah, I see. I didn't realise configure had a --user switch as well. A stop-gap might be to generate a more helpful error message: ghc-pkg --global list <check for deps> if unsatisfied dep ghc-pkg list if dep is satisfied now, print "Perhaps configure with --user?" IMH and not so informed opinion, I think the defaults should be close to autoconf's, if only by the principle of least surprise. Thanks! cheers peter
