It looks like the Web-MeetMe Project Page URL listed at http://www.freepbx.org/support/documentation/module-documentation/third-party-unsupported-modules/web-meetme-support#comment-46889 is DEAD.

Should be changed to either
http://www.fonicaprojects.com/web-meetme/meetme_control.php?s=5
or
http://sourceforge.net/projects/web-meetme/

i haven't tested if the module code itself is current/good.
