warnings module used in setup.py but never imported

[zerothi]

Title says it all,

you have a warnings.warn in your setup.py but nowhere is the package loaded!

This is a build bug in 1.0.3 which makes pip fail in some cases...

Thanks for reporting this! It is being addressed in #495

Great, I thought creating a pr was too much of a hazzle :)

I'll close since it is already merged.
