Where "fixed" is a /very/ strong word as it implies there's actually a 
problem.  You can ignore the errors if you like.

It just means that your binaries were built without libudev support, so 
you're falling back to the code that does things the hard way and gets 
errors like you saw.  Install libudev (including development headers), 
and you'll have a proper build...  Or, just use a packaged build if 
you're not actually modifying MythTV source code.
