Sometime after experiencing this problem I discovered that my ports had 
suffered from the accidental introduction of some packages which had 
been built for rev. 6.4 (see the thread under 
http://lists.freebsd.org/pipermail/freebsd-questions/2010-January/210421.html). 
As a result of this I had to completely remove and re-install all my 
ports and I haven't seen the "leave_playpen" problem since then. It 
might be just coincidence or it may be that pkg_info just got confused 
by all the links to wrong and non-existent libraries. Could it be that 
the ports in your main system are corrupt but those in the jail are 
clean?
