Hi Dale,

thanks for your informations... :)

I did a typo...instead of 

     "apt-get python smbus".

it must be

     "apt-get python-smbus".


I am searching "python-smbus" for Gentoo.
The kernel configuration is already setup and ok.

Do you the know the translation 

of "python-smbus" (Debian-speak)

to ??? for Gentoo?

Thank you very much in advance!
Best regards,
Meino
