Thanks, I've applied to master. However, I have a comment below.

I've applied because you've followed how it's already done for this
package, but I'm not super happy with how it's done. Indeed, pulseaudio
configure script has explicit enable/disable options such as
--enable-bluez4, --enable-bluez5, --enable-openssl, etc.

And it would be a lot better to use them. One benefit is that if we
pass --enable-bluez4, but there is a dependency missing, pulseaudio
configure.ac script will bail out with an error, instead of silently
ignoring and building without pulseaudio support.

Would you be interested in reworking the pulseaudio package to take
advantage of those --enable/--disable options?

One example is that the bluez support (either 4 or 5) requires the sbc
library... which is not expressed at all in the current pulseuadio.mk.

Thanks!

Thomas
