Just a remark. I didn't touch the Mac binaries for a long while (and
my mac is already resting in peace, so I cannot test).
Have any new binaries been released in the meantime?

I usually remove the "--make" switch (or it may be enough to call
--keep switch once?) to prevent remaking formats at any given time if
no updates are there. Is it possible that the make switch is turned
out on your computer as well?

(Sorry, but I really cannot test what's going on on mac, though it's a
bit strange that it behaves differently.)
