Compaq has released their Tru64 shared libs for use with Netscape on
"alpha linux" (not to mention FreeBSD & NetBSD..):
http://www.compaq.com/partners/netscape/downloads/register_nav4_Linux.html

This is a form which has a survey on it.  Make sure to tell them
you're running ({Free,Net}BSD ;-). When you fill out this form, you
get pointed at a 16MB rpm.  When you finally manage to extract it (I
HATE rpms!), you end up with a tar file:
usr/local/netscape/netscape-all-4.7.tar.gz

To make it run on FreeBSD (note you need XFree86 installed!):

mkdir /compat/osf1
cd /compat/osf1
tar zxf /path/to/netscape-all-4.7.tar.gz
mkdir /compat/osf1/usr/lib
ln -s /usr/X11R6/lib/X11 /compat/osf1/usr/lib/
edit /compat/osf1/usr/bin/netscape & make it look like this:

#!/bin/sh
#
# Set up environment for Netscape on Alpha Linux and then run Netscape.
# From www.alphalinux.org/docs/netscape_du.shtml.
# Provided by Compaq Computer Corporation, Alpha Technology Solutions Group.
#
#export LD_LIBRARY_PATH=/usr/shlib
export MOZILLA_HOME=/compat/osf1/usr/local/netscape
exec $MOZILLA_HOME/netscape $* 


Then run /compat/osf1/usr/bin/netscape


Cheers,

Drew
