>Description:
I am building mail/mailman from ports. I need to override the default User ID and Group ID for the Mailman user.

mail/mailman automatically assigns MM_USERID=91 to the mailman user, and then uses the value of MM_USERID to set the value for MM_GROUPID. 

    [root at host /usr/ports/mail/mailman]# grep USERID Makefile 
    MM_USERID?=     91
    MM_GROUPID?=    ${MM_USERID}
            @${ECHO} "MM_USERID=91          The user ID of the Mailman user."
            @${ECHO} "MM_GROUPID=MM_USERID  The group ID for the Mailman user."


My environment already has a user with the UID=91 and GID=91. I need to set a different UID and GID for the Mailman user.

However, when I use standard methods to override the value in the Makefile [1], make appears to ignore this value and reports the wrong value. This is misleading and should be fixed:

    [root at host /usr/ports/mail/mailman]# make MM_USERID=501 
    ===>  License GPLv2 accepted by the user
    ===>  Found saved configuration for mailman-2.1.14_6
    
    You may change the following build options:
    MM_USERNAME=mailman     The username of the Mailman user.
    MM_USERID=91            The user ID of the Mailman user.
    MM_GROUPNAME=mailman    The group to which the Mailman user will belong.
    MM_GROUPID=MM_USERID    The group ID for the Mailman user.
    MM_DIR=mailman          Mailman will be installed in /usr/local/mailman.
    CGI_GID=www             The group name or id under which your web server executes CGI scripts.
    IMGDIR=www/icons        Icon images will be installed in /usr/local/www/icons.

I also tried adding `MM_USERID=501` to /etc/make.conf, as suggested at [2], but make still says `MM_USERID=91`.

>How-To-Repeat:
1. cd /usr/ports/mail/mailman
2. Try to change the UID for 'mailman' using `make MM_USERID=501`
3. Look in the log and notice now Make still reports 'MM_USERID=91'.
