---------------------------------+------------------------------------------
 In a special case the logging procedure writes a useless log file. Here a
 port has to be activated in order to build a dependent port. But the
 activation fails and results in a useless, self-referencing log file.

 The following example is a demonstration of the bug in the wild:

 {{{
 $ port -v outdated py26-docutils
 The following installed ports are outdated:
 py26-docutils                  0.5_1 < 0.6_0
 $ port -v installed py26-roman
 The following ports are currently installed:
   py26-roman @1.4.0_0
 $ sudo port upgrade py26-docutils
 --->  Computing dependencies for py26-docutils
 --->  Activating py26-roman @1.4.0_0
 Log for py26-roman is at:
 /opt/local/var/macports/logs/_Users_raim_src_macports_trunk_dports_python_py26-roman/main.log
 Error: The following dependencies failed to build: py26-roman
 Error: Unable to upgrade port: 1
 To report a bug, see <http://guide.macports.org/#project.tickets>
 }}}

 The resulting log file:
 {{{
 $ port log py26-roman
 --->  Activating py26-roman @1.4.0_0
 Log for py26-roman is at:
 /opt/local/var/macports/logs/_Users_raim_src_macports_trunk_dports_python_py26-roman/main.log
 }}}

 {{{
 $ cat
 /opt/local/var/macports/logs/_Users_raim_src_macports_trunk_dports_python_py26-roman/main.log
 version:1
 :msg:main --->  Activating py26-roman @1.4.0_0
 :msg:main Log for py26-roman is at:
 /opt/local/var/macports/logs/_Users_raim_src_macports_trunk_dports_python_py26-roman/main.log
 }}}
