After I run 'sudo port upgrade outdated', I got the following.


--->  Computing dependencies for orbit2
--->  Deactivating orbit2 @2.14.19_0+universal
--->  Cleaning orbit2
--->  Activating orbit2 @2.14.19_1+universal
--->  Cleaning orbit2
Error: Requested variants "" do not match original selection "+universal".
Please use the same variants again, perform 'port clean gconf' or
specify the force option (-f).
Error: Unable to upgrade port: 1
To report a bug, follow the instructions in the guide:

Should I run 'sudo port -f clean gconf'? I'm not sure if there is some
unwanted consequence.
