I just rebuilt mythtv-0.27_p20140321 in my up to date ~amd64 desktop
and it built fine and it runs good.
Then I built 0.27.1_p20140713 and it is broken.

I have no problem building it by hand and it goes to /usr/local (which
is on path) so plain running ldconfig will do it.
However, I have no clue how to build specific commit ID. Something I
have to learn ...

Thanks!
