There must be a bug in the code that was added from
<https://github.com/macports/macports-base/pull/20>. Has a ticket been
opened for this problem?

It would be easy enough to dodge the immediate error with 'info exists',
but the non-existence implies that the ports are being processed in the
wrong order. An affected user will probably need to run some modified
reclaim code to generate extra debug output to help figure out what is
going wrong.
