One more thing, as I tried to rebuild whole python I've encountered on
following problem:
building '_multiprocessing' extension
gcc -fPIC -fno-strict-aliasing -g -O2 -DNDEBUG -DHAVE_SEM_OPEN=1
-DHAVE_FD_TRANSFER=1 -DHAVE_SEM_TIMEDWAIT=0 -IModules/_multiprocessing -I.

build/lib.solaris-2.9-sun4u-2.7/_multiprocessing.so
*** WARNING: renaming "_multiprocessing" since importing it failed: ld.so.1:
python: fatal: relocation error: file
build/lib.solaris-2.9-sun4u-2.7/_multiprocessing.so: symbol sem_timedwait:
referenced symbol not found
so I had to commented out HAVE_SEM_TIMEDWAIT from setup.py, see:
elif platform.startswith('sunos5'):
macros = dict(
HAVE_SEM_OPEN=1,
HAVE_FD_TRANSFER=1
)
#HAVE_SEM_TIMEDWAIT=0,
libraries = ['rt']
thanks
