How does one enable import of a module from some package?
[snip] Apparently using uickCheck-1.2.0.0.conf to pick module name is not right. However, using names from: /usr/lib/ghc-6.12.1/package.conf.d/QuickCheck-2.1.0.2.conf and in particular: Test.QuickCheck works. I should have read: http://www.haskell.org/ghc/docs/6.12.2/html/users_guide /packages.html#package-databases more closely, and in particular: You can see GHC's package table by running GHC with the -v flag. which showed: hiding package QuickCheck-1.2.0.0 to avoid conflict with later version QuickCheck-2.1.0.2 Sorry for noise. -regards, Larry
