[syslog-ng]res_init not found on Solaris 9

[joe781@att.net]

I am using Libol 0.3.5 and syslog-ng 1.5.23. Libol installed without a problem.
The make for syslog-ng terminates as follows:


gcc  -g -O2 -Wall -I/usr/local/include/libol -D_GNU_SOURCE  -o syslog-ng  main.o

*** Error code 1
make: Fatal error: Command failed for target `syslog-ng'
Current working directory /usr/local/src/syslog-ng-1.5.23/src

The ./configure step finds it OK. Where would I find it? TIA.
