configure warnings and errors upon ./configure for Pinentry v0.9.7

[David Adamson]

Hello,

I'm running a debian Jessie v8 kernel release 3.16.0-4-amd64 on my
personal laptop. It came pre-installed with GnuPG 1.4.18.

I went to generate keys for myself by typing:
gpg2 --gen-key

But then during the process got this error:
gpg: agent_genkey failed: No pinentry
Key generation failed: No pinentry

So I assumed I needed to install Pinentry and downloaded it from gnupg.org.
I tried running ./configure as root and towards the end I got the
following warnings and errors. I'm not sure how many issues I'm
dealing with here or how to fix them.

I appreciate any help, thanks.
