netscape 4.08 illegal instruction

[Vincent Murphy <theDon@cs.ucc.ie>]

 i used contrib/netscape4 to install the netscape navigator 4.08 tarball
from ftp.netscape.com.  whenever i try to run it, it dies and i get this:

$ /usr/local/netscape/netscape &
[1] 4976
$ 
[1]+  Illegal Instruction     /usr/local/netscape/netscape
$

 should i use the communicator tarball or try navigator 4.07?  any info
would be much appreciated.

 TIA..
