 I noticed that a new version of the links browser is available.

 Attached is a port file diff.

 I removed the second master_site because apparently it's not been updated
 since 2005.

 I removed the x11 description to silence lint and because the default
 description recommended by lint is equivalent.

 Tested under osx 10.7 without x11
