System: NetBSD rickb.iaw.on.ca 1.2C NetBSD 1.2C (RICKB) #2: Sun Mar 16 22:11:38 EST 1997 root@rickb.iaw.on.ca:/usr/src/sys/arch/i386/compile/RICKB i386


>Description:
Whereis searches the kernel's path by default, which is pretty lame IMHO.  
I've added a quick -p option to whereis which will make it search the users 
path as specified in their environment instead.
	
>How-To-Repeat:
Try to "whereis" someing in /local/bin
	
>Fix:
Apply the following patch.
