[Dovecot] Dovecot configure script for 1.0b8 not including SQL drivers?

[Will Buik]

I am having a problem with the configure script for Dovecot 1.0b8.  It
doesn't seem to be compiling in sql engine driver support.  I have
specified --with-sql and --with-pgsql but when the script is done it
says "Building with SQL drivers ..............:" but lists no drivers
afterwards.  I tried compiling it anyway but it logs the error "
auth(default): Unknown database driver 'pgsql' " so the it defiantly
didn't get compiled in.  My pgsql includes and libs are in a non
standard location but I specified that in the CPPFLAGS and LDFLAGS
before the ./configure invocation.  What have I done wrong here, or is
there a bug in the script?

The whole invocation is:
CPPFLAGS='-I/usr/local/openssl-0.9.8b/include
-I/usr/local/pgsql-8.1.4/include'
LDFLAGS='-L/usr/local/openssl-0.9.8b/lib -L/usr/local/pgsql-8.1.4/lib'
./configure --prefix=/usr/local/dovecot-1.0b8
--sysconfdir=/etc/dovecot --localstatedir=/var --with-ioloop=eooll
--with-notify=dnotify --without-pop3d --with-storages=maildir
--with-sql --with-pgsql --with-gnu-ld

Thanks in advance.
