Which version of pthreads?
Which version of OpenLDAP?
What configure options/environment settings are you using?
Is configure complaining?
What's the first error from a fresh make?

>/usr/local/pthreads/bin/pgcc [...] -llthread -lV3
>/bin/ld: Duplicate symbol "pthread_create" in files /tmp_mnt/auto/src/ldap/libraries/liblthread.a(thread.o) and /usr/local/pthreads/lib/libpthread.a(pthread.o)

I suspect ./configure did not like the pthread_create() in the
standard libraries and tried to -DNO_THREADS which mimics pthreads.

You can verify this by checking results in include/portable.h.

You might try to use gcc and passing the appropriate CPP and LDFLAGS
(but not the -lpthread) to configure.
	CC=gcc
	CPPFLAGS=-I/usr/local/pthreads/include
	LDFLAGS=-L/usr/local/pthreads/lib
	./configure

passing -lpthread in LIBS should be avoided so that libraries can (if
possible) be built to support both threaded and non-threaded applications.

Probably failed to compile.

Not a good idea.

They should be in <unistd.h> which is included by <ac/unistd.h> (on HP-UX 10.20,
per their man page). Your configuration must have gone astray.
