Michael, this is great info. you made two changes: -g1 -> -g -O1 -> -O2 Does -g -O1 work on PPC-OSX? We really want to "turn down" the level of optimization used while compiling the SWIG stuff. The SWIG stuff is not performance critical, and using a lower level of optimization speeds up the compilation.
