I poked around a bit more and remembered what it is that makes it work:
you need an -install_name switch when building libpq.dylib (and then the
link of psql has to be sure to reference that .dylib file). For example
I see this as part of the libpq link step:

-install_name '/Users/tgl/testversion/lib/libpq.5.dylib'

after having configured with "--prefix=/Users/tgl/testversion".

So this works only if your libpq.dylib is actually installed at the
location that was expected when you built it. The recipe you gave
looks like it should have done that, but I'm suspicious that the
answer is somewhere near here.
