 I tried to upgrade my outdated ports, which include encfs. The port
 upgrade encfs stopped with the following error:

 {{{

 I found a similar error under the ticket #40494 for the aria2 package. The
 complete log file is attached.

Comment:

 Ah, then we should have this port use the cxx11 1.0 portgroup.
