Ack! Swarm installation woes...

[Richard Hanschu]

OK...here is the progress I have made in the last 24 hrs. (of which I 
am damn proud of being a brand new UNIX HPUX admin :)

Running HP/UX 10.10 on a 715 box

Installed: (and working AFAIK)
libXpm
Tcl/TK
BLT
libtclobjc
swarm

After quite a bit of work, swarm complies w/o obvious complaint. 

Now the problem... when I untar the applications and gmake heatbugs 
or mousetrap (the only two I have tried)  it seems to compile 
Heatbug.m through HeatbugBatchSwarm.m w/o problems then bombs making 
the executable with:

collect2: ld returned 1 exit status
/bin/ld: Unsatisfied symbols:
   __builtin_va_start (code)
gmake: *** [heatbugs] Error 1

Any ideas?
I was able to fix all of the earlier problems, but this one leaves me 
stumped as to even where to start....

TIA,

P.S. I am wanting to explore Swarm with the idea of making a 
simulation for the evolution of virus virulence in various 
populations. Anyone out there using swarm for exploring evolution (as 
opposed to community ecology)?
