I can only guess that gpg-agent has not been properly installed, in
spite of your successful compilation and installation.

Is gpg-agent pointing to the right pinentry program?  It probably
defaulted to one under /usr/local/ but I suspect that yours lives
under /usr/ - edit ~/.gnupg/gpg-agent.conf as appropriate and restart
gpg-agent.

A work around (not the orthodox solution I'm afraid) would be to enter
in ~/.gnupg/gpg-agent.conf a line that should point to the real location
of pinentry in your system.

Something like:
pinentry-program "path to pinentry"
