So on cygwin it is "final" executable. Thanks - I start to get the picture. What is odd is that 'cygport install' puts the _wrapper_ into /usr/bin rather than the executable, and does not install the exectable. The wrapper just silently fails. Now maybe if I built the package (as if I were the package maintainer) and installed that with cygwin's setup, I would get the right thing - not sure (and not 100% sure how to do that). Cheers - EM
