Uh, so what did you do *exactly*?

initdb completed successfully.  I didn't try running any tests beyond
that; I'm not sure that we have any regression tests that will exercise
ICU locales.

Yeah, but notice that only two of the three interesting ICU libraries
are actually linked into the postgres executable so far as otool and
the dynamic linker are concerned.  I suspect that the other one,
libicudata, is dynamically loaded by the ICU code --- and in your
configuration it fails to find that library.  The error message is
not definitive that that's what's happening, but it's suggestive.
If that's the right interpretation, it means that setting
DYLD_LIBRARY_PATH allows that third library to be found, but whatever
you did doesn't.

I still think that this represents under-engineering by the ICU crew
and not anything we're doing wrong.

BTW, when I skimmed the "readme.html" docs in the ICU sources this
morning, I noted that there were multiple ways you could configure
it to find the ICU data.  I did not read in detail, figuring that
their default configuration would be sane, but maybe that was an
overly charitable assumption.
