I made no such absurd assumption (unless you only read the title). As I 
mentioned, this would only be seen by firewire, XVMC, and openGL so it 
would not be noticed by 'everyone' and might cause confusion.

The has_library() routine manually includes /lib and /usr/lib rather 
than relying on the ld.so.conf. So why not remove those then? I think 
the default behavior is supposed to mirror what the linux linker/loader 
(ld.so) looks for by default.

If /lib64 and /usr/lib64 do not exist in /etc/ld.so.conf, then how does 
ldd finds them on a 64-bit system for every other application?
If I do an ldd on mythfrontend, all the linked libraries are from 
/usr/lib64. That tells me the confgure script detection logic is what is 

And regardless, inst Fedora/Centos a pretty widely used distro to 
ignore? This seems like a pretty simple one or two line fix to
