Bugzilla Bug 204748

The 0.9.8 ebuilds (all versions I think) disable the loading of the hal-detect
module, if the hal use flag is not set:

      if ! use hal; then
                sed -i -e '/module-hal-detect/s:^:#: ; /module-detect/s:^#::'
"${D}/etc/pulse/default.pa"
        fi

This breaks on 0.9.8 since the default.pa provided by pulseaudio already has an
.ifexists to load module-hal-detect only when it exists. The replace applied by
the ebuild now doesn't only uncomment the load directive, but also the
.ifexists directive. Since it doesn't remove the .else and .endif directives,
this leaves default.pa with a syntax error and pulsaudio won't start.

Reproducible: Always

Steps to Reproduce:
USE=-hal emerge pulseaudio
pulseaudio

Fixed in 0.9.9 series.
