Comment(by raimue@…):

 I reproduced the issue with a new port `foo` which has a dependency on
 less:
 {{{
 sudo port deactivate less
 sudo touch /opt/local/bin/less
 }}}

 {{{
 $ sudo port install foo
 --->  Computing dependencies for foo..
 --->  Activating less @436_0
 Error: activating less @436_0 failed: Image error: /opt/local/bin/less
 already exists and does not belong to a registered port.  Unable to
 activate port less. Use 'port -f activate less' to force the activation.
 Log for less is at:
 /opt/local/var/macports/logs/_Users_raim_src_macports_trunk_dports_textproc_less/main.log
 Error: The following dependencies failed to build: less
 Error: Status 1 encountered during processing.

 }}}

 Looks much better now.

 But is the "Log for $port is at:" message supposed to be in the log file?
