perc.mtc.in fails?

I'm trying out MCSim 4.2.0 and I'm getting an error from the perc.mtc.in 
example.  All of the other examples run without trouble.  Here's the output:
Testing NDoses with perc.ndoses.in ...
-PASSED-
Testing Monte Carlo with perc.mtc.in ...
make: *** [one] Error 1
Any ideas what is wrong?  I'm using GCC 3.2 under Solaris 8.
