Looks like poldek does not recognize R:(post, postun) and fails to
install packages even though dependencies are present:

$ ag '^R.*post' mpd.spec
86:Requires(post,postun):	gtk-update-icon-cache
87:Requires(post,preun,postun):	systemd-units >= 38

$ poldek --cmd desc -r mpd |grep gtk-update-icon-cache
Requires(pre):  /bin/sh, /bin/sh, gtk-update-icon-cache, systemd-units >= 38
Requires(un):   /bin/sh, /bin/sh, gtk-update-icon-cache, systemd-units >= 38

$ poldek -u mpd
...

Manual installation of gtk-update-icon-cache followed by installation of
mpd is all fine.
