>Description:
When bsd.destdir.mk iterates over $_DESTDIR_MOUNT_LIST it runs:

# realpath $_destdir/__temp__

Due to changes in realpath (prior to June 2012) this causes a non-zero exit.  This then causes the make to fail.

>How-To-Repeat:
On a freshly built installation, attempt to perform a 

# make config DESTDIR=/usr/local/jails/imap1
===>  Creating some important subdirectories
realpath: /usr/local/jails/imap1/___temp___: No such file or directory
*** [do-chroot] Error code 1

>Fix:
Change /usr/ports/Mk/bsd.destdir.mk

_full_dest_path=`${REALPATH} $${_destdir}/$${_dest_path}`; \

to:

_full_dest_path=`${REALPATH} -q $${_destdir}/$${_dest_path} || :`; \


This may not be the proper fix, but it works around the issue.
