The pa_idxset functions are provided by libpulsecommon-X.Y.so (X.Y is
the pulseaudio version). libpulsecommon is used by libpulse, and it
seems that there's some problem with linking libpulsecommon to
libpulse. libpulsecommon is installed in ${libdir}/pulseaudio/, so it's
not in the standard search path for libraries, but libpulse should have
 the directory recorded in it so that the linker can find
libpulsecommon. For me this objdump command shows the directory, you
can start by checking that on your machine (you'll need to change the
libpulse location, since it's probably not under /usr/local):

    $ objdump -p /usr/local/lib/libpulse.so.0 | grep RUNPATH
      RUNPATH              /usr/local/lib/pulseaudio
