New description:

 after running "port mdmg xxx" once, then rebuilding one of "xxx's"
 dependencies, then running "port mdmg xxx" a second time, it responded
 like this:

 {{{
 $ port mdmg rdp-projects
 ...
 (it rebuilds mplayer-edl, which has changed)
 --->  Staging mplayer-edl into destroot
 ...
 --->  Creating disk image for rdp-projects-0
 --->  Disk Image for rdp-projects-0 is up-to-date
 }}}

 and appears not to recreate the .dmg file, even though dependencies had
 changed so..I guess this is a bug?

Comment:

 According to the code, the mtime of the disk image is compared to the
 mtime of the portfile. If the disk image is newer, it is considered to be
 up to date. Dependencies are not considered. This could be considered a
 bug. To work around it, you can manually delete the old disk image to
 allow MacPorts to create a new one.
