Milter-greylist

Hello,

I have recently tried to upgrade mg from version 4.3.2 to 4.3.4 on Tru64
UNIX.
I used the same configuration options and make as with the previous
version.

Now I got the following warning at the end of the configure stage:

config.status: WARNING:  'Makefile.in' seems to ignore the --datarootdir
setting

At startup time of the new binary I got the following message:

legacy configuration file '/etc/mail/greylist.conf' is used instead of
'/usr/local/etc/mail/greylist.conf'. IT SHOULD BE RENAMED!

I got as well the following error soon after startup and the mg exits:

milter-greylist:
mkstemp("/usr/local/var/milter-greylist/greylist.db-HlnPA0pY") failed:
No such file or directory

Was there any incompatible changes which I am not aware of?
Or it should just work as before and there is a bug on that platform?

Bests,
Attila
