Portal Server Webserver Installation Failure?

I'm installing SP3 on Solaris 7. Getting 'libplc3.so: open failed: no such file' during install of the SUNWwtws (NES) package. I searched for libplc3.so and did not find it anywhere on my server... Where does this file come from? I am attempting a straight-forward install at this point. Thanks!

Check if the package SUNWwtws is already installed. You can check this using

#pkginfo SUNWwtws

If found, remove the package using 'pkgrm' and then continue with a fresh installation. The file 'libplc3.so' is usually found in /opt/netscape/server4/instances/bin/https/lib which means an instance of the Web Server is running thus clashing in the installation of SUNWwtws package.
