System: NetBSD polaris 1.3 NetBSD 1.3 (POLARIS) #0: Thu Mar 26 13:17:18 MST 1998 root@polaris:/usr/src/sys/arch/i386/compile/POLARIS i386


>Description:
If you set PREFIX="", install a package, and then try to pkg_delete it.. 
pkg_delete dumps core instantly.  Obviously PREFIX="" is completely 
bogus, but the program definately shouldn't respond in such a violent 
manner.  The program is attempting to change directory to "" and dying.

	
>How-To-Repeat:
Install a package with PREFIX="" and pkg_delete it.

	
>Fix:
Make pkg_delete sanity check before it does a chdir, print a warning 
message and exit.. rather than abrubtly exploding on the user.  Perhaps 
assuming / instead of NULL would be better, and still allow pkg_delete to 
do it's job.
