This looked like an issue with the library search path. i was able to get around this modifying LD_LIBRARY_PATH
LD_LIBRARY_PATH=/usr/local/lib
# export LD_LIBRARY_PATH
But, now I get the below error,
# /opt/soe/local/syslog-ng-3.3.7/sbin/syslog-ng
Error opening plugin module; module='afsocket', error='Unsatisfied data symbol \'rfc931_timeout\' in load module \'/usr/lib/hpux32/libwrap.so\'.'
