pinentry-mac never displays any UI

[Richard Bronosky]

I've had no luck with the binary version that I downloaded based on
Benjamin's various howtos and mailing list messages.  I have
downloaded the source, and poked around it in Xcode.  I wanted to make
sure that there was a GUI element to the pinentry-mac.app.  There is.
I built it and tried placing both the build and debug versions in
/Applications.  I've also downloaded and compiled pinentry-helper.c
and placed it inside /Applications/pinentry-mac.app/Contents/MacOS/
and set ~/.gnupg/gpg-agent.conf to try it.

Nothing works.  Same result in all cases.  The pinentry-mac icon
bounces, but I have no UI to speak of.
