The following is from Jakub 

"The symbols you mentioned are available in NPTL only, not in
LinuxThreads. By default threaded programs are compiled/linked against
LinuxThreads, so that they can be run against both LinuxThreads and NPTL
(the latter is the default runtime version though). If you want to
specifically create a NPTL only program, you need to compile/link
(on RHEL3) with:
-I /usr/include/nptl -L /usr/lib*/nptl/"

So on your installation try:

find /usr -name nptl
...
/usr/include/nptl
...
/usr/lib/nptl
/usr/lib64/nptl

Then plug-in the specific include and library paths for your system and 
compile target.
