compile time error using newly installed redhat 5.2 and swarm 3.1

[Matthew M Murphy]

I just installed redhat 5.2 and Swarm (as well as the necessary additional
packages), however upon trying to compile the demo applications, I run
across an error.  Below is the output from the compiler after I type make 
(for heatbugs):

/usr/bin/libtool-swarm --mode link egcs -g -O2 -fno-inline

If anyone can offer an opinion about the meaning of this error and what I
might do to correct it, I would much apprecaite it.
