This is only a warning.  It should not matter.

Where did main.o come from?  Can you post the compiler output from  
when it was built?

That is to be expected if any of the objects in the link have been  
built without '-arch ppc'.  I suspect you have some (static)  
libraries from Fink, Darwinports or other sources and these are being  
used instead of the ppc versions from the Swarm ftp site.  Check  
carefully what is listed on the link line.

Are you using the CFLAGS from the Swarm Makefiles within your  
makefile?  Unless you do it won't work.  The whole point of the Swarm  
makefiles is to set up the environment for your machine.  Have a look  
at the Heatbugs makefile for clues.

Make sure you are using the shell initialization script provided in / 
usr/local/swarm2.2/etc/swarm.
