 My build of the trunk as started failing with the error below. Presumably
 there is a missing link to the pthread library routines. This began some
 time after 05/05/2012 and 05/12/2012.

Comment:

 You need to give us more information than that.  We had the same problem
 on our debian buildbot slave, and the fix was to do:

 apt-get build-dep mythtv

 (IIRC).  Basically, your system libraries are incomplete.  If this doesn't
 work, please let me know, and I'll dig into exactly what packages you are
 missing.
