There should be a '-arch ppc' in these lines.  If it is not in this  
line, it will not have been in the compile commands for the object  
files Heatbug.o etc..  So the object files are i386 code and the link  
will fail.

It looks as if you have not properly modified /usr/local/swarm2.2/etc/ 
swarm/Makefile.common.

Lines 26 to 36 in that file should look like this:
CC = gcc -B ../../tools
CFLAGS =  -g -O2 -arch ppc -Wno-long-double
CPPFLAGS =  -D_GNU_SOURCE
EXPORT_EXTERN = @EXPORT_EXTERN@
IMPORT_EXTERN = @IMPORT_EXTERN@
SED = /usr/bin/gsed

OBJC=gcc -B ../../tools
OBJCFLAGS= -g -O2 -arch ppc -Wno-long-double -B $(top_srcdir)/tools - 
fgnu-runtime -fno-strict-aliasing -Wall -Wno-import -Wno-protocol - 
Wno-long-long $(EXTRAOBJCFLAGS)

GNUSTEPLIBINCLUDES =

If you add the '-arch ppc' options to the CFLAGS and OBJCFLAGS as  
above and then do a clean rebuild of heatbugs, it will work.  The  
rest of your transcript shows that you are linking the right libraries.
