Cqn you explain how this separate Poly/ML is compiled, and where it is

The Mac OS X crash report should tell you about the shared libraries that 
were used in the failed process.

There is also "otool -L" to check that statically on the executable, but I 
am unsure if it is exactly that.  E.g. for polyml-5.5.0-3/x86-darwin/poly 
from our Isabelle component it always shows the location where the binary 
was compiled originally, regardless of DYLD_LIBRARY_PATH at run-time.
