rebuild of a jail uses old DESTDIR

[jdyke]

i had built a jail a few weeks ago as a learning expierence, specifying a 
DESTDIR of /usr/jail/ssh for make world, i don't really want it to reside there 
long term and want to build it with less features enabled in make.conf. So now 
I'm trying to build another jail in another location and `make world 
DESTDIR=/path/to/new/dir` fails with
--------------------------------------------------------------
 >>> Building an up-to-date make(1)
--------------------------------------------------------------
make: don't know how to make /usr/jail/ssh/usr/lib/libc.a. Stop


I've run a make clean and make cleandir and tried to re run without success. 
i'm currently running a grep to look for the old path in any file on the whole 
system, /etc/ and /usr similar greps came up empty.

How can i make the system forget about the old DESTDIR?  Should i just delete 
all of /usr/src and cvsup?

thanks for any assistance
