[SPARCbook] Netscape on SB2 Solaris 1.0.1 --- how?

[BSD Bob]

Anyone know of a usable Netscape or similar webscraper that will run on
a SparcBook 2 using Solaris 1.0.1?  I can almost get the sunos4.1.3 port
to run (Netscape 4.0.8), but it seems to be not finding something.
The same port works fine on OpenBSD on a Sparc SS1 or IPX.
Any suggestions for a usable browser are appreciated.

Thanks

Bob
