Broken MOVED handling

[bdrewery]

textproc/p5-ack was moved to textproc/ack:

 ===>>> Starting check of installed ports for available updates
 ===>>> The textproc/p5-ack port moved to textproc/ack ===>>> Reason: Not just a perl module
 ===>>> Update p5-ack-1.96_1? y/n [y]
 ===>>> Launching child to reinstall p5-ack-1.96_1
 ===>>> All >> p5-ack-1.96_1 (1/1)
 ...
 ===>>> Port directory: /usr/ports/textproc/ack
 ===>>> The following actions will be taken if you choose to proceed:
         Install textproc/ack
 ===>>> Proceed? y/n [y]

Afterwards, both p5-ack and ack are installed.

 [ Rotluchs] bdrewery: it looks fine at least until the recursive self-invocation            
 [ Rotluchs] + exec /usr/local/sbin/portmaster -d -n -o textproc/ack p5-ack-1.96_1           
 [ Rotluchs] it must go wrong at some point after that...
