To build OpenCollada: * apply this patch http://wiki.blender.org/index.php/File:Opencollada@675.diff * build by typing 'scons XMLPARSER=expatnative' (pcre and expat must be installed) * after build, copy all compiled libs into 'lib' (Blender build will refer to it): rm -rd lib mkdir lib find . -iname '*.a' | xargs cp -t lib
