Component:  base                 |     Version:  1.7.0                                
 Keywords:  livecheck            |        Port:

 Using MacPorts installed from latest trunk:
 {{{
 port -d livecheck glibmm
 DEBUG: Port (livecheck) version is 2.18.1
 DEBUG: Fetching http://freshmeat.net/projects-xml/glibmm/glibmm.xml
 DEBUG: The regex is
 "<latest_release_version>(.*)</latest_release_version>"
 DEBUG: The regex matched
 "<latest_release_version>2.14.2</latest_release_version>", extracted
 "2.14.2"
 glibmm seems to have been updated (port version: 2.18.1, new version:
 2.14.2)
 }}}

 In this case, the current port version is 2.18.1 but freshmeat
 is not up to date and the latest version on record there is
 2.14.2.

 Livecheck assumes that the latest version from freshmeat is, in fact, the
 latest version of the port and declares it so
 after only checking to see that the freshmeat version is not
 equal to the port version.

 In this case, I believe livecheck should check to see that the port
 version is greater than the freshmeat latest version and
 therefore the port seems to be up to date.

 In otherwords, the highest version from the livecheck URL
 should be considered a new version only if it is greater than
 the port version.

 Have only observed this when freshmeat is selected by default
 due to no explicit livecheck declarations as in glibmm but
 it occurs in several instances (freshmeat doesn't seem
 to be very good at keeping up to date).  So can't say whether
 this faulty comparison occurs with any other livecheck URLs in
 similar circumstances.
