As a complete newbie, I had to install linux 2.2 several times before I got all the kinks worked out. Each time I downloaded netscape 2.76 from ftp.netscape.com. I'd get the error message "libstdc++=libc6.1-1.so.2 not available". I solved that by linking it to libstdc++=libc6.1-2.so.3, which is probably not relevant, but I don't know for sure. Anyway, it worked.
The last time I re-installed, I used netscape 3.? from the Debian distribution. It worked, but was hopelessly outdated. So I downloaded 4.76 again and installed it over my 3.? installation. When I ran it, I got a "bus error" message. Thinking that some files from my 3.? version wer still around causing incompatibitites with 4.76 stuff, I ripped everything out and re-installed 4.76. I still got the "bus error" message. I don't have a clue about how to troubleshoot this problem. Can anyone help? Thanks!
