-------------------------------------+--------------------------------------
 hugin-app's CMakeLists.txt file has hardcoded strings /opt/local and
 /Applications/MacPorts; this will do the wrong thing if the user is not
 using the default values of ${prefix} or ${applications_dir}. The port
 should fix CMakeLists.txt to handle these situations correctly.

 In fact there are several other source files that hardcode /opt/local and
 /sw which might need to be fixed as well.
