the real nslookup is in the bind package. it should probably be
separated from that and either put into an nslookup package or included
in the dnsutils package.

other people have explained why this happens, here's a solution for you:

try installing the ash package, and writing a netscape wrapper script which
looks something like:

    #! /bin/ash

    SHELL=/bin/ash
    export SHELL

    exec /path/to/netscape -options -and-more-options


Then modify whatever it is that launches netscape (e.g. FVWM button bar) to
run the ash wrapper script instead.

(alternatively, name this script "netscape" and put it in the first
directory in the PATH)
