This is our hack to find the right .dylib; perhaps you can add the location of the dylib that you need to the list and get it to work? If you cannot find the right . dylib (which is actually just a link to the os.path.join(prefix,'Python') file you could make your own dummy libpython.dylib and point to that?</div><div><br></div><div><br></div><div> Good luck and let us know how it goes,</div><div><br></div><div> Barry</div><div><br></div><blockquote type="cite"><div dir="ltr"><div><br></div><div>Thank you very much</div><div>Amal</div></div>
