conftest.c:8:28: error: ac_nonexistent.h: No such file or directory about openvpn-auth-ldap HOT 3 OPEN

Here is the config.log

Now when I run the ./configure command I dont see any errors, but still the 
openvpn-auth-ldap.so is not being created, seems the configure is still not 
running and finishing the job:

See above the latest config.log

I checked the log files again and found this:

configure:4575: gcc -o conftest -g -O2 conftest.c -lpthreads >&5
/usr/lib64/gcc/x86_64-suse-linux/4.3/../../../../x86_64-suse-linux/bin/ld: 
cannot find -lpthreads
collect2: ld returned 1 exit status
configure:4581: $? = 1
configure: failed program was:
| /* confdefs.h. */
| #define PACKAGE_NAME "auth-ldap"


I have the lpthreads installed:

# find / -name libpthread*
/usr/lib64/libpthread_nonshared.a
/usr/lib64/libpthread.so
/usr/lib64/libpthread.a
/usr/lib/libpthread_nonshared.a
/usr/lib/libpthread.so
/usr/lib/libpthread.a
/lib64/libpthread-2.11.3.so
/lib64/libpthread.so.0
/lib/libpthread-2.11.3.so
/lib/libpthread.so.0

Does this look good? And how can I point to the libpthread files?
thx
