ERROR! You must have the Lame MP3 encoding library installed to compile MythTV.
If you think configure made a mistake, make sure you are using the latest
version from SVN.  If the latest version fails, report the problem to the
mythtv-dev@mythtv.org mailing list or IRC #mythtv on irc.freenode.net
Include the log file "config.err" produced by configure as this will help
solving the problem.
