I've been investigating the possibility of porting Swarm to Power Macs for
a year now, and as far as I know there's currently no way to do this.  The
problem is that there is no Obj C compiler for the Power Mac (or for any
other platforms using POWER or PowerPC chips), due to a "feature" of the
gcc Obj C runtime.  gcc will produce code for 680x0 Macs (I assume this is
what you used for MachTen), but it won't produce Obj C code for PPC (nor is
there a good gcc port to the MacOS, as opposed to MachTen). (Stepstone
offers an Obj C compiler for 680x0 Macs (under MPW) -- you might also be
able to get Stepstone's source and try to port it to the PPC, but I'm not
sure if this would help you much, since it's a different dialect of Obj C.)

If you want the gory details on the gcc Obj C problem, see:

There's a hack of sorts for AIX, along with Cygnus's view of the problem, at:
