python-boto obsolete?

[Andreas Heckel]

I was running "cygcheck-dep -o" and received 
python-boto: is obsoleted by ( python2-boto )

When trying to uninstall python-boto, setup claims that package "duplicity-0.7.11-1" still depends in it.

So far I have no experience with cygcheck-dep and only used setup to keep my system updated. 
Hence I am uncertain, how to interpret this sort of discrepancy.

Cheers,
Andreas
