How to test my build of gpg2?

[Andrey Jivsov]

I wonder what's the process of running my own build of gpg2?

I am getting the error:
> gpg: agent_genkey failed: Unsupported certificate
> Key generation failed: Unsupported certificate

when I generate a default RSA key, as bellow. I think this is where the 
password dialog would come up.

I think I followed all the steps that I did in the past that were 
needed, but I am getting an error. There used to be a pinentry, but I 
don't see it being built now, so I didn't do any replacement for the 
pinentry.

The code is the latest from git+ssh://playfair.gnupg.org/git/gnupg

Thank you.

I launched my own version of the agent:

I made sure that the libraries that I built are used:
