Just an FYI, I tried using [which] on Mac OS X and got this:

/Users/hans/code/pure-data/trunk/externals/mrpeach/which/ 
which.pd_darwin: dlopen(/Users/hans/code/pure-data/trunk/externals/ 
mrpeach/which/which.pd_darwin, 10): Symbol not found: _filelength

_filelength() looks like a Microsoft function.
