Uh, true. I misread that as "change the portfile". Just touching the portfile without changing its contents does nothing as far as the current version of MacPorts is concerned. MacPorts used to compare the modification date of the portfile with the modification date of the statefile, but now it compares the checksum of the portfile's contents with the checksum recorded in the statefile.

If the goal is to clean the work directory, change the portfile or run "sudo port clean" before fetching/extracting/patching/configuring/building/destrooting/installing.

If the goal is not to clean the work directory, don't change the portfile or use the "-o" flag when fetching/extracting/patching/configuring/building/destrooting/installing.
