I managed to solve the problem - the solution is on the MythTV wiki. 
Ubuntu doesn't look for lib files in /usr/local/lib. You need to edit 
/etc/ld.so.conf and add /usr/local/lib to the end, then run sudo ldconfig.

I am surprised that the MythTV itself managed to compile without errors. 
I suppose it doesn't require anything in /usr/local/lib.
