[syslog-ng] Syslog-ng 2.0.3 compile error

Hi, I am trying to configure syslog-ng 2.0.3 on solaris 10 and below is the error checking for EVTLOG... Package eventlog was not found in the pkg-config search path. Perhaps you should add the directory containing `eventlog.pc' to the PKG_CONFIG_PATH environment variable No package 'eventlog' found configure: error: Cannot find eventlog version >= 0.2: is pkg-config in path? I have installed libnet-1.20 and libol-0.3.18, then ran ./configure from /syslog-ng-2.0.3. Am I missing something? Thanks, Ravi Kumar P.
