The bz2 module isn't compiling for me on Solaris 8: building 'bz2' extension gcc -g -Wall -Wstrict-prototypes -fPIC -I. -I/export/home/python/dist/src/./Include -I/usr/local/include -I/export/home/python/dist/src/Include -I/export/home/python/dist/src -c /export/home/python/dist/src/Modules/bz2module.c -o build/temp.solaris-2.8-sun4u-2.3/bz2module.o cc1: warning: changing search order for system directory "/usr/local/include" cc1: warning: as it has already been specified as a non-system directory /export/home/python/dist/src/Modules/bz2module.c: In function `Util_CatchBZ2Error': /export/home/python/dist/src/Modules/bz2module.c:120: `BZ_CONFIG_ERROR' undeclared (first use in this function) /export/home/python/dist/src/Modules/bz2module.c:120: (Each undeclared identifier is reported only once ... This particular machine has a /usr/include/bzlib.h file with a copyright date of 1998. There are several other BZ_*_ERROR defines, but not BZ_CONFIG_ERROR.
