You are right about the dependencies - that isn't ideal,
but it isn't the only myth library with that problem.
libmythui also has cross-dependencies with libmyth.



I did test builds on Mac OS X (GCC 4.0.1) and Linux
(GCC 4.1.2, GNU ld 2.17) without problems.


I will try to remove the libmyth dependencies
from libmythupnp as soon as possible,
but as a hacky workaround for you,
try having alternating libraries on the link line.
e.g. -lmythupnp-0.20 -lmyth-0.20 -lmythupnp-0.20
