MacOS X uses DYLD_LIBRARY_PATH.

Hoever even with that it doesn't work for me. Look in unix/tclLoadDyld.c and
you'll find this:

    dyld_return = NSAddLibrary(native);

Looking at the docs it seems that NSAddLibraryWithSearching(native) (IIRC)
should then search DYLD_LIBRARY_PATH, but changing that _still_ didn't work
for me. In the end I had to manually implement it myself in tcl before calling 
load.

Note that there also seems to be a bug in MacOS X where if "native" is a file
that does not exist then instead of returning a failure (as the docs state)
the process simply exits! Wonderful...
