[Dovecot] issues with 2.1b1 on OS X

Two issues came up for me when building 2.1beta1 on OS X (10.5.8 on PPC). The first was already mentioned in an earlier thread by a BSD user (http://dovecot.org/list/dovecot/2011-September/061201.html). I just wanted to point out that the error is still occurring in spite of a new test for GNU ld in the configure script. I needed to remove "-no-undefined" specifically:

#NOPLUGIN_LDFLAGS="-no-undefined"
if test "$with_gnu_ld" = yes; then
  NOPLUGIN_LDFLAGS="$NOPLUGIN_LDFLAGS -Wl,--as-needed"
fi

More important, Dovecot aborts on launch with the following error:

Nov 19 10:23:52 kerio2 dovecot[33553]: master: Fatal: kevent(EV_ADD,
READ, 16) failed: Invalid argument

I configured using the same args as I had used successfully on 2.0.15: --with-gssapi --with-ldap --with-sql --prefix=/opt/dovecot-2.X.X. I also tried an exact copy of my known-good config from 2.0.15, to no avail.

Thanks, Tony
