Comment (by ShadSterling):

 The port that was failing after `sstrings` seems to have been fixed, now
 `port clean all` fails after `xvega-bindings`

 Using `sudo port -d clean --all all` to get debug info now (runs for
 almost an hour and) generates output ending with

 Which appears to fail on port `XviD`

 The bug here is that `port` doesn't include the failing port name in the
 normal output
