This patch allows dynamic loading to work on Mac OS X (without using the dl* compatibility API included with Mac OS 10.3). A couple of notes: 1) Mac OS X distinguishes between two types of "shared libraries": dylibs, which are meant to be linked at compile-time (and automatically loaded by the dynamic linker at runtime), and bundles, which are meant to be loaded "by hand", via explicit API. This implementation of the Parrot_dl* API attempts to hide the distinction and "do the right thing" for either case, but the two types of libraries do act differently--they are manipulated via different API, and among other differences dylibs cannot be unloaded (bundles can be), and bundles aren't searched for in any standard locations (dylibs can be). 2) The ncurses-life demo works partially with this patch applied--ncurses is clearly invoked (there is a generation count in green, counting up on a black background), but there doesn't seem to be any "life" animation. But I suspect that this is not a library loading issue. 3) There's some logging still in place which should be cleaned up long-term (maybe once Parrot_dlerror is implemented), but which is useful for the moment. (For instance, the ncurses-life demo will log when it fails to find its libraries without an extension.) JEff
