Ian,

As I previously pointed out - there is a separate download for Intel and PPC 
versions of J for OS X - has anyone experimented with -d32 in 10.5 and 
earlier?? I haven't seen any indication of that and it might well work just 
fine - again, don't worry about the PPC version (which will only run up to and 
including OS 10.5...)

- joey
