Proto attempts to call invoke() on an ArrayIterator

[mfollett]

When running proto.pl config proto dies with a stack trace complaining that invoke() is not implemented on an ArrayIterator. Log at bottom.

Thanks,
Matt Follett

mfollett@gc-mattbook> perl proto.pl config
A typical usage is:
'./proto install '
Available commands: fetch refresh clean test install uninstall showdeps showstate help upgrade
