 I wanted to install again PianoBar which is CLI client for Pandora Music.
 But I got such dependency info before install:

 what the hell PERL is doing in app that essentialy streaming audio? I can
 understand all the codecs library, but why Xorg-libX11? Terminal is
 terminal there is nothing to to with Windows!
 Could someone contact developer and ask about explanations?
 Overall it looks very cluttered.
