#50527: 'sudo port clean' fails
----------------------+--------------------------------

     Type:  defect    |     Status:  new
 Priority:  Normal    |  Milestone:
Component:  ports     |    Version:  2.3.4
 Keywords:            |       Port:
----------------------+--------------------------------
 I was performing a 'upgrade outdated' and ran into the issue:
 $ time sudo port upgrade outdated
 Password:
 --->  Computing dependencies for qwt61
 Error: Unable to exec port: Can't install qwt61 because conflicting ports
 are active: qwt52
 To report a bug, follow the instructions in the guide:
     http://guide.macports.org/#project.tickets

 The next step is to do a 'sudo port clean' as near as I can tell, but that
 appears to have confused itself.

 $ sudo port clean
 Can't map the URL 'file://.' to a port description file ("Could not find
 Portfile in /Users/xok").
 Please verify that the directory and portfile syntax are correct.
 To use the current port, you must be in a port's directory.
