See 
http://peak.telecommunity.com/DevCenter/setuptools#declaring-extras-optional-features-with-their-own-dependencies 
for how to define "extras".  You would then tell people to install 
YourPackage[A] or YourPackage[B] to select which optional dependency they 
want to use.

There is no way to simply choose one to install at random, however.  :)
