Testparm Error HPUX - DLD.SL Library

[Shimek, Kirk]

HP_UX 10.20 / SAMBA2.0.6 / gcc

Compiles just fine.  Run the "testparm /opt/samba/lib/smb.conf" command
and get the following error . . .

"/usr/lib/dld.sl: Unresolved symbol: vsnprintf (code) from testparm
Abort (coredump)"

What are the pre-requisite(s) for libraries for Samba to function or is this
a
known error / fix.  Please, could someone respond with a push in the right
direction or the definitive answer.   TIA
