how to get libresolve.so.2 lib

Dear list,
I run Solaris 2.5.1. I try to install a compiled version of Netscape
Communicator 4.07.
After succsessfull install I try to start it, but I get an error message
saying I need libresolve.so.2.
Please, could someone point me out
1. If this library can run under Solaris 2.5.1?
2. Where it can be taken from?

Thank you.
