Reverting the argument, this means that the buildd only believed the
dependency was satisfied while in fact it wasn't after a human's
intervention. I don't believe that buildd admins deliberately did
this... There might have been some bug causing this, but hardware
failures also sometimes manifest as apparently "random" behavior.
And, by the way, I think that evidence is more for the view that it
wasn't a complete package that was missing, but rather only particular
files - at least this was the case previously when mysql-dfsg-5.0
failed.

Fortunately not, since my packages hardly suffered FTBFSes, and the ones
they caused where of a different nature.

Ah - can you point me to something to read about this? How can it be
architecture-specific, or host-specific?
