I don't know about 64 bit SuSE, I'm only running it on a 32 bit Intel box.

No, it is not possible to use both NPTL and LinuxThreads at the same 
time in a single program. OpenLDAP doesn't care which thread library you 
use as long as it supports the POSIX threads specification.

You should look in the config.log file to see why it failed to find the 
threads library.
