Can't install Mail SPF

I'm trying to install Mail SPF following the tutorial but don't let me install it , i tried 4 times always after trying to install Module::Build

 

What tutorial (URL) are you using? And which distribution?

 

this tutorial : http://www.howtoforge.com/postfix_spf

debian sarge

 

You can try this instead:

Code:

apt-get install libmail-spf-query-perl

 

Is there any other config options required when using the apt-get?

And is it possible to add in the tutorial that this is an option if install Mail::SPF with cpan doesnt work.
