I had to comment out some stuff in its "setup.py" to persuade the _multiprocessing C shim to use sem_open() (remove freebsd7 and/or freebsd8 from that file before "python setup.py config" and "python setup.py build"). I was running the Doc/includes/mp_benchmarks.py file which ships with multiprocessing. multiprocessing is part of Python 2.6 base now, so likely what is Not OK in the backport, would need to be forward-ported when it is happy with sem_open() in Python 2.5. cheers BMS --------------030408070501040503000606 Content-Type: text/plain; name="sch" Content-Transfer-Encoding: base64 Content-Disposition: inline; filename="sch" KGdkYikgYnQKIzAgIDB4MDAwMDAwMDgwMGE5ZWM3YyBpbiBrc2VtX29wZW4gKCkgZnJvbSAv bGliL2xpYmMuc28uNwojMSAgMHgwMDAwMDAwODAwYTk1MDRkIGluIHNlbV9vcGVuICgpIGZy b20gL2xpYi9saWJjLnNvLjcKIzIgIDB4MDAwMDAwMDgwMTMxODQyYyBpbiBzZW1sb2NrX25l dyAoKQogICBmcm9tIC91c3IvbG9jYWwvbGliL3B5dGhvbjIuNS9zaXRlLXBhY2thZ2VzL211 bHRpcHJvY2Vzc2luZy0yLjYuMS4xLXB5Mi41LWZyZWVic2QtNy4xLVNUQUJMRS1hbWQ2NC5l Z2cvbXVsdGlwcm9jZXNzaW5nL19tdWx0aXByb2Nlc3Npbmcuc28KIzMgIDB4MDAwMDAwMDAw MDQ0YmM3MyBpbiBQeVR5cGVfSXNTdWJ0eXBlICgpCiM0ICAweDAwMDAwMDAwMDA0MTUxZDMg aW4gUHlPYmplY3RfQ2FsbCAoKQojNSAgMHgwMDAwMDAwMDAwNDZlNTViIGluIFB5RXZhbF9F dmFsRnJhbWVFeCAoKQojNiAgMHgwMDAwMDAwMDAwNDcxNzRjIGluIFB5RXZhbF9FdmFsQ29k ZUV4ICgpCiM3ICAweDAwMDAwMDAwMDA0YWZiZGEgaW4gUHlDbGFzc01ldGhvZF9OZXcgKCkK IzggIDB4MDAwMDAwMDAwMDQxNTFkMyBpbiBQeU9iamVjdF9DYWxsICgpCiM5ICAweDAwMDAw MDAwMDA0MWFlMGQgaW4gUHlDbGFzc19Jc1N1YmNsYXNzICgpCiMxMCAweDAwMDAwMDAwMDA0 MTUxZDMgaW4gUHlPYmplY3RfQ2FsbCAoKQojMTEgMHgwMDAwMDAwMDAwNDZlNTViIGluIFB5 RXZhbF9FdmFsRnJhbWVFeCAoKQojMTIgMHgwMDAwMDAwMDAwNDcxNzRjIGluIFB5RXZhbF9F dmFsQ29kZUV4ICgpCiMxMyAweDAwMDAwMDAwMDA0YWZiZGEgaW4gUHlDbGFzc01ldGhvZF9O ZXcgKCkKIzE0IDB4MDAwMDAwMDAwMDQxNTFkMyBpbiBQeU9iamVjdF9DYWxsICgpCiMxNSAw eDAwMDAwMDAwMDA0MWFlMGQgaW4gUHlDbGFzc19Jc1N1YmNsYXNzICgpCiMxNiAweDAwMDAw MDAwMDA0MTUxZDMgaW4gUHlPYmplY3RfQ2FsbCAoKQojMTcgMHgwMDAwMDAwMDAwNDRmOTM4 IGluIF9QeVR5cGVfTG9va3VwICgpCiMxOCAweDAwMDAwMDAwMDA0NGJjYjggaW4gUHlUeXBl X0lzU3VidHlwZSAoKQojMTkgMHgwMDAwMDAwMDAwNDE1MWQzIGluIFB5T2JqZWN0X0NhbGwg KCkKIzIwIDB4MDAwMDAwMDAwMDQ2ZTU1YiBpbiBQeUV2YWxfRXZhbEZyYW1lRXggKCkKIzIx IDB4MDAwMDAwMDAwMDQ3MTc0YyBpbiBQeUV2YWxfRXZhbENvZGVFeCAoKQojMjIgMHgwMDAw MDAwMDAwNGFmYmRhIGluIFB5Q2xhc3NNZXRob2RfTmV3ICgpCiMyMyAweDAwMDAwMDAwMDA0 MTUxZDMgaW4gUHlPYmplY3RfQ2FsbCAoKQojMjQgMHgwMDAwMDAwMDAwNDFhZTBkIGluIFB5 Q2xhc3NfSXNTdWJjbGFzcyAoKQojMjUgMHgwMDAwMDAwMDAwNDE1MWQzIGluIFB5T2JqZWN0 X0NhbGwgKCkKIzI2IDB4MDAwMDAwMDAwMDQ0ZjkzOCBpbiBfUHlUeXBlX0xvb2t1cCAoKQoj MjcgMHgwMDAwMDAwMDAwNDRiY2I4IGluIFB5VHlwZV9Jc1N1YnR5cGUgKCkKIzI4IDB4MDAw MDAwMDAwMDQxNTFkMyBpbiBQeU9iamVjdF9DYWxsICgpCiMyOSAweDAwMDAwMDAwMDA0NmU1 NWIgaW4gUHlFdmFsX0V2YWxGcmFtZUV4ICgpCiMzMCAweDAwMDAwMDAwMDA0NzE3NGMgaW4g UHlFdmFsX0V2YWxDb2RlRXggKCkKIzMxIDB4MDAwMDAwMDAwMDQ2ZmVmNCBpbiBQeUV2YWxf RXZhbEZyYW1lRXggKCkKIzMyIDB4MDAwMDAwMDAwMDQ3MDZmZCBpbiBQeUV2YWxfRXZhbEZy YW1lRXggKCkKIzMzIDB4MDAwMDAwMDAwMDQ3MTc0YyBpbiBQeUV2YWxfRXZhbENvZGVFeCAo KQojMzQgMHgwMDAwMDAwMDAwNDcxODYyIGluIFB5RXZhbF9FdmFsQ29kZSAoKQojMzUgMHgw MDAwMDAwMDAwNDhhZTAyIGluIFB5X0NvbXBpbGVTdHJpbmcgKCkKIzM2IDB4MDAwMDAwMDAw MDQ4YWVkNiBpbiBQeVJ1bl9GaWxlRXhGbGFncyAoKQojMzcgMHgwMDAwMDAwMDAwNDhjMzcz IGluIFB5UnVuX1NpbXBsZUZpbGVFeEZsYWdzICgpCiMzOCAweDAwMDAwMDAwMDA0MTIyMTkg aW4gUHlfTWFpbiAoKQojMzkgMHgwMDAwMDAwMDAwNDExODk3IGluIG1haW4gKCkK --------------030408070501040503000606--
