Bad files on buildports-lion-x86_64

[Marko Käning]

David,

I had this in the past with RKWard already twice!!

Check what we’ve done in rkward's pre-activate phase, where we did
delete the left-over files previously, but have disabled the “delete”
commands ATM as we want to understand when those files got created.

Mac OS Forge folks never reacted to any of my queries regarding checking
on files, so stop waiting and do make use of the pre-activate phase as well!!

Greets,
Marko
