Hey all, [...]
in which case i'd like to know how to clean up DP|MP xithin my box because for example i have :
%> port installed apache2 @2.2.0_0 apache2 @2.2.2_1 apache2 @2.2.3_0 (active)
i think it is at leasst unusefull the let the apache2 old versions on my box rather more or les "dangerous".
then how to uninstall an old versio after a successfull install of a new one ?
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...)
