No. This problem in  cyclic dependences  in mythtv libraries.

for example, libmythui depends on libmyth and libmyth depends on libmythui:
$ ldd /usr/lib/libmyth-0.20.so|grep myth
         libmythui-0.20.so.0 => /usr/lib/libmythui-0.20.so.0 (0xb79d0000)
$ ldd /usr/lib/libmythui-0.20.so|grep myth
         libmyth-0.20.so.0 => /usr/lib/libmyth-0.20.so.0 (0xb7c6b000)

If your build system has ld with enabled --as-needed flag by default - 
you program cannot be build with not correct libraries (libraries with 
unresolved symbols).

Also, i use "hasher" for build mythtv - this is special build tool from 
ALT Linux. Hasher create build chroot environment for every package from 
packages repository.

It look as installing linux for building every package, and *mythtv* not 
included to installed packages list.
