 I wanted to install an old version of opencv (2.3.1a) so that I did the
 following.

 {{{
 svn co -r 86729
 http://svn.macports.org/repository/macports/trunk/dports/graphics/opencv
 cd opencv/
 sudo port -v install +apache2+postgresql83
 }}}

 Then I got errors in the middle:

 {{{
 ...
 Command failed:  cd
 "/opt/local/var/macports/build/_Users_tkim2_Packages_opencv/opencv/work/OpenCV-2.3.1"
 && /usr/bin/make -j2 -w all
 Exit code: 2
 Error: org.macports.build for port opencv returned: command execution
 failed
 ...
 }}}

Comment:

 The log you attached was not from a
 [http://guide.macports.org/chunked/project.html#project.tickets.prerequisites
 clean build], but errors I see in it appear to relate to ffmpeg:

 {{{
 error: ‘av_open_input_file’ was not declared in this scope
 }}}

 This old version of opencv is probably not compatible with the new version
 of ffmpeg we have in MacPorts. You could try installing a correspondingly
 older version of ffmpeg too.
