	The linux compatibility libs attemps to load other
	linux libs using an absolute path rather than
	traversing the LD_LIBRARY_PATH vector.

	I am running FreeBSD3.2, and tried to use the linux
	version of netscape 4.61:

communicator-v461-us.x86-unknown-linux2.0.tar.gz

	I invoke netscape as follows:

#!/bin/sh
XNLSPATH=/usr/X11R6/lib/X11/nls
XAPPLRESDIR=/usr/compat/linux/var/X11R6/lib/app-defaults
XCMSDB=/dev/null

MOZILLA_HOME=/usr/local/netscape-linux

LD_LIBRARY_PATH=\
/usr/compat/linux/var/X11R6/lib:\
/usr/compat/linux/lib:\
/usr/compat/linux/usr/openwin/lib:\
/usr/compat/linux/usr/X11R6/lib:\
/usr/compat/linux/usr/lib:\
/usr/compat/linux/usr/i486-linuxaout/lib:\
/usr/lib:\
/usr/X11R6/lib:\
/usr/local/lib

XKEYSYMDB=$MOZILLA_HOME/XKeysymDB

CLASSPATH=$MOZILLA_HOME/java/classes:/usr/local/share/java/java

export XKEYSYMDB XNLSPATH XAPPLRESDIR MOZILLA_HOME LD_LIBRARY_PATH \
        CLASSPATH XCMSDB

$MOZILLA_HOME/netscape $* -geometry 1150x985+0+0 &


	When I visit www.netscape.com, netscape crashes and dumps core.

	Running gdb on netscape:

% gdb -e /usr/local/netscape-linux/netscape -c netscape.core

/lib/ld-linux.so.1: No such file or directory.
#0  0x28bf43c5 in ?? () from /usr/compat/linux/lib/libc.so.5
(gdb) quit


	As you can see, /usr/compat/linux/lib/libc.so.5 tried to load
	ld-linux.so.1 by specifying an absolute pathname, rather
	one prepended with /usr/compat/linux.


	Cheers,

	Joe
