Yes, because now it's finding the system readline, which isn't actually readline (Apple ships a "readline" which is actually BSD "editline", so you get missing symbols for things editline doesn't support such as completion). I think you'll need to temporarily deactivate MacPorts' iconv instead of using --extra-lib-dirs.
This can't really be fixed by either GHC or MacPorts; there doesn't seem to be a good solution as yet, although the MacPorts folks may end up implementing a hacky solution because Apple has introduced *another* MacPorts-breaking library conflict in Lion (libnotify).
Yep, this is Apple's problem and everyone else just has to put up with it.
Thanks. That got lambdabot happy and installed. For the record (and for the lazyweb): $ sudo port deactivate -f libiconv $ cabal install lambdabot $ sudo port activate libiconv
If you want to mix macports and a non-macports ghc, I think the best solution is to self-compile ghc against the macports libiconv. This is easy, just configure ghc with
./configure --with-iconv-includes=/opt/local/include --with-iconv-libraries=/opt/local/lib
I haven't had a problem since I started building ghc this way (10.5 and 10.6).
I may try that with a source install for the next release of the Haskell Platform. Thanks again everyone, -- Adam
