Active port install isssue

[Scott Haneda]

Clean install of my never-ending ASSP portfile project...

Error: Target org.macports.activate returned: Image error: /opt/local/ 
bin/spfquery is being used by the active p5-mail-spf port.  Please  
deactivate this port first, or use 'port -f activate p5-mail-spf- 
query' to force the activation.

I am not sure I understand this one. I know how to work around it, but  
I am looking for how to make the problem not be a problem for a user  
who is installing.

Here is the list of depends:
depends_lib \
                     port:p5-compress-zlib \
                     port:p5-digest-md5 \
                     port:p5-digest-sha1 \
                     port:p5-email-mime-modifier \
                     port:p5-email-send \
                     port:p5-email-valid \
                     port:p5-file-readbackwards \
                     port:p5-io-socket-ssl \
                     port:p5-libwww-perl \
                     port:p5-mail-spf \
                     port:p5-mail-spf-query \
                     port:p5-mail-srs \
                     port:p5-net \
                     port:p5-net-cidr-lite \
                     port:p5-net-dns \
                     port:p5-net-ip-match-regexp \
                     port:p5-net-senderbase \
                     port:p5-net-syslog \
                     port:p5-perl-ldap \
                     port:p5-sys-syslog \
