Hi, i was trying to install durus 2.0 on a clean OS X Tiger powerbook (not mine ;-( and the build step reports the following: building 'durus._persistent' extension gcc -fno-strict-aliasing -Wno-long-double -no-cpp-precomp -mno-fused-madd -fno-common -dynamic -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -I/System/Library/Frameworks/Python.framework/Versions/2.3/include/ python2.3 -c _persistent.c -o build/temp.darwin-8.1.0-Power_Macintosh-2.3/_persistent.o _persistent.c:6:20: Python.h: No such file or directory _persistent.c:7:26: structmember.h: No such file or directory .... The gcc being used is gcc-3.3, but i also tried with gcc-4.0. These files should come from the python installation? It is using the one that "comes" with the system, i.e.: $ python Python 2.3.5 (#1, Mar 20 2005, 20:38:20) [GCC 3.3 20030304 (Apple Computer, Inc. build 1809)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> but, as the machine was "initialised" from an older powerbook that was running panther, I have no idea if there is some confusion between the 2. BTW, same problem when trying to install quixote. How do I fix this? Thx, mario
