We need more info about the host where this failed to help you :)

 * What operating system? (and what version of the OS?)

 * What version of gpg?

 * What version of pinentry are you expecting to use?

 * If you do the following command from the shell, do you see a pinentry
   show up anywhere?

      printf "option ttyname $(tty)\ngetpin\n" | pinentry
