I get the following with the package for Mac OS X 10.2: [...]

I get the impression from Google Groups that rebuilding from the source will fix this.

Basically, yes. However, in order to rebuild GHC from source, you need a working copy of GHC :-).

Is there a Jaguar binary, source drop, or should I rebuild?

Just check the mailing list:

From: Wolfgang Thaller Date: Fre Aug 30, 2002 22:43:34 Europe/Graz To: GHC List Subject: GHC on Mac OS X 10.2 (Jaguar)

The new Mac OS X 10.2 has arrived, and GHC has stopped working. I've compiled a new GHC binary that runs on 10.2 (but not anymore on 10.1). It is available at: http://www.uni-graz.at/imawww/haskell/JaguarGHC.tar.gz

This archive contains just a new GHC binary, the rest of the binary release already has to be already installed.

What happened: With Mac OS X 10.1, Apple had included a 'curses' library in it's main 'libSystem.dylib' library. For 10.2, they removed that, and instead added a separate ncurses library (which wasn't included in 10.1.). GHC relies on one of those libraries (via readline), but readline has to be recompiled to use the other library. GHC-compiled programs that don't explicitly link against readline are not affected by this problem.

Cheers, Wolfgang
