Hi All (maybe just Jim? ;-) ), Just did a buildout involving zope.interface and got: Getting distribution for 'zope.interface'. ******************************************************************************** WARNING: An optional code optimization (C extension) could not be compiled. Optimizations for this package will not be available! Python was built with Visual Studio 2003; extensions must be built with a compiler than can generate compatible binaries. Visual Studio 2003 was not found on this system. If you have Cygwin installed, you can try compiling with MingW32, by passing "-c mingw32" to setup.py. ******************************************************************************** Got zope.interface 3.5.1. Any chance someone could roll and release a Windows binary egg for this? cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk
