No, I doubt that.  The symbol it is having problems linking with is
defined in $GEMS/common/util

The issue here is that Ruby/Opal Makefiles will build the object files.
Then to build a Simics module, we use the Virtutech Makefile which may be
using a different compiler.  The compilers do not seem to agree on the
names of mangled symbols.

This problem comes up frequently on the list.  We currently do not have a
clear, bullet-proof solution.
