port configure dovecot

[Bradley Giesbrecht]

Why would the current dovecot Portfile want to build mysql5 when I do  
"port configure dovecot +mysql5"?

brad at trex ~ $ port installed mysql5
The following ports are currently installed:
   mysql5 @5.1.41_0 (active)

brad at trex ~ $ file /opt/local/bin/mysql_config5
/opt/local/bin/mysql_config5: symbolic link to `/opt/local/lib/mysql5/ 
bin/mysql_config'

brad at trex ~ $ file /opt/local/lib/mysql5/mysql/libmysqlclient.dylib
/opt/local/lib/mysql5/mysql/libmysqlclient.dylib: symbolic link to  
`libmysqlclient.16.dylib'


 From dovecot:Portfile
variant mysql5 description {Enable MySQL support} {
     depends_lib-append          path:bin/mysql_config5:mysql5
     archcheck.files-append      lib/mysql5/mysql/libmysqlclient.dylib
     configure.args-append       --with-mysql
     configure.ldflags-append    -L${prefix}/lib/mysql5/mysql
     configure.cppflags-append   -I${prefix}/include/mysql5/mysql
}
