I was able to reproduce this error by faking a file named
'AEST-10AEDT-11,M10.5.0,M3.5.0' in /usr/share/zoneinfo/ on Mac OS X.
(As far as I know, OSX is not that different from BSD with respect to
basic posix interfaces.)

$ cd /usr/share/zoneinfo/
$ sudo cp EST AEST-10AEDT-11,M10.5.0,M3.5.0

Is it possible that the buildbot has such a file?  What I find strange
is that autoconf logic tests for working tzset using exactly the same
TZ spec:

"""
        putenv("TZ=AEST-10AEDT-11,M10.5.0,M3.5.0");
        tzset();
        if (localtime(&groundhogday)->tm_hour != 11)
            exit(1);
#if HAVE_TZNAME
        if (strcmp(tzname[0], "AEST") || strcmp(tzname[1], "AEDT"))
            exit(1);
#endif
"""  See 'configure' script.

In other words, if TZ=AEST-10AEDT-11,M10.5.0,M3.5.0 breaks tzset, this
should be detected at the configure stage and the tzset tests should
be skipped.   Is there a way to force configure run on the bot?
