Ack, and my bad -- I should have checked. 

The packaging is much smarter than I gave it credit for and _does_ of course
include a call to ldconfig in its postinst.  So maybe next time you want to
try 'apt-get source -b jags' (after adding a deb-src entry that points to
unstable to your /etc/apt/sources.list) ?
