Description:
Today i play a little bit with mpd.
After some tests i also want to play an Audio CD and read about the cdio_paranoia plugin.
So i called "mpd --version" and realize that there is no support for this plugin.
I download the PKGBUILD files and look at it but could not see any reason for not supporting the plugin.
So i call makepkg and got my cdio_paranoia support.
So it seams that the feature set is depending on the installed packages of the building system.
As this could lead to different feature sets depending on who build the package i think this is some kind of bug.

Additional info:
* package version(s): 0.19.7-1

Steps to reproduce:
* install mpd
* do: mpd --version
* download PKGBUILD and build it
* do: src/mpd-0.19.7/src/mpd --version
* see the differences

for me its:
