>Description:
	
When an older libmilter is already installed, trying to compile milter-greylist
fails with:

...
checking if -D__EXTENSIONS__ is needed to use snprintf... no
checking for smfi_register in -lmilter... no
checking for smfi_register in -lmilter -lsm... no
checking for smfi_register in -lmilter -lsmutil... no
Required libmilter not found. Use --with-libmilter
*** Error code 1

Stop.
make[1]: stopped in /usr/pkgsrc/mail/milter-greylist
*** Error code 1

Stop.
make: stopped in /usr/pkgsrc/mail/milter-greylist


Updating libmilter, then retrying milter-greylist succeeds. Note that 
the version both before and after success is libmilter-8.16.1nb1.
MKPIE?
