[pulseaudio-discuss] pulseaudio daemon not responging

Exactly the same problem as mine.

1. Build of pulseaudio failed without libpthread-stubs.so with "no
such file ..."
2. I noticed that in crux linux, sem_wait() resides in
libpthread_stubs.so, and it is found through call to libpthread.so,
but in my arch linux box there are no libpthread_stubs.so at all. So,
I think that sem_wait() (in my arch linux box) resides in
libpthread.so.

Is it possible to upgrate libpthread.so? Which package I must upgrade?
I cannot just delete libpthread-stubs.so.

Finally, I see something strange when run ./configure of
libpthread-stubs-0.2 source code (which is currently in use of my
distro).
Here is output snippet after running ./configure:
....
....
checking for pthread_cond_wait... yes
checking for pthread_cond_signal... yes
checking for pthread_cond_broadcast... yes
checking for pthread_equal... yes
checking for sem_init... no
checking for sem_destroy... no
checking for sem_wait... no  -> HERE!!!
checking for sem_trywait... no
....
...
