Thanks, Paul and Bjorn. Indeed, this did the trick. Any thoughts why ./configure claimed to have discovered readline on its own, but then was unable to use it? Or maybe, for some reason, the message is unrelated? -- Denis

Hi, initially, I faced the same problem. i.e., ghc-pkg: dependency readline doesn't exist (use --force to override) Thus, I tried ./configure --with-readline-include=/opt/local/include/readline -- with-readline-libraries=/opt/local/lib and build again, then I hit another error, Preprocessing library readline-1.0.1.0...

There are two separate tests: (1) whether your installed GHC claims to have a readline package, which succeeded, and (2) whether the C library for readline can be found, and this latter test failed. The build itself should not have failed though - it should just have built GHC without readline support. I think I fixed the bug that caused this recently, and I'll make sure the fix gets merged into 6.8.2.
