Nope, same error.
Just a thought here, on my 4.-10 system, I've got
which all have pthread_mutex_trylock, couldn't it be forced to link
against one of them?
Also, since we're using gtk2, wouldn't beep-media-player (gtk2 fork
of xmms) be a better choice, or an option?
attached is the build/install log, (build.txt) if it'll help any.
