Note that all the library files you show under your /usr/lib are in
fact for 0.20 and not 0.20.2.  If I list them on my gentoo install I
see this:

ll /usr/lib/libmyth-*
lrwxrwxrwx 1 root root      24 Aug 28 12:38 /usr/lib/libmyth-0.20.2.so
-> libmyth-0.20.2.so.0.20.2
lrwxrwxrwx 1 root root      24 Aug 28 12:38
/usr/lib/libmyth-0.20.2.so.0 -> libmyth-0.20.2.so.0.20.2
lrwxrwxrwx 1 root root      24 Aug 28 12:38
/usr/lib/libmyth-0.20.2.so.0.20 -> libmyth-0.20.2.so.0.20.2
-rwxr-xr-x 1 root root 2880104 Aug 28 12:38 /usr/lib/libmyth-0.20.2.so.0.20.2

Are you sure you did 'make install' after compiling mythtv?  Also, did
you expressly specity a prefix of /usr, or are the 0.20.2 libraries
possibly in /usr/local/lib?
