 Thanks Nando. Btw, i relate the NPTL support with the
"sem_open : function not implemented" problem because
i've websearched a lot about this mysterious issue,
and from what i gathered it seems is related with
patching and recompiling the kernel and forgetting to
enable NPTL (the RH9 default kernel has NPTL support)
