Netscape Communicator v.5 won't run ?

[Mike Rae <MRae@uunet.ca>]

All :

After installing Navigator 4.5, and attempting to run, I get the
following error messgae 

"./netscape: can't load library 'libXpm.so.4"

Running a "ldd netscape" tells me that

"libXpm.so.4 => not found"
"libg++.so.27 => not found"
"libstdc++.so.27 => not found"

What am i missing ?
