It is not dangerous, it only means you have three versions built on your system, but the only one that can work is the one active, lying in ${prefix} (the other (in fact, all installed versions, the active version only makes links to this place) are kept in ${prefix}/var/db/dports/software/) that way you can roll back to an older version if the new one does not work well. However, it takes space on your hard drive.
To uninstall one version, just use "uninstall", for example sudo port uninstall apache2 @2.2.0_0
To do a rollback, you have to deactivate the active version then activate the older one, for example:
sudo port deactivate apache2 @2.2.3_0 sudo port activate apache2 @2.2.2_1

(I do not know about your ruby problems...)
