In the first case you generate a public key no matter which library
you have installed.
In the second case you generate a private key, but only if you are on 2.5.
Do you need a public key or a private key?
If you need a public key, just use 2 arguments.
If you need a private key and you want it to work with all pycrypto
versions, go and look for the remaining 2 parameters (p and q)... ;-)

I would simply assume it will have problem with previous versions:
it's clearly off spec for them.
