Created attachment 283593 [details] Build log. The net-misc/rdesktop uses pkgconfig util during building. I propose to add it into DEPEND. Package doesn't builds without pkgconfig. The error is: configure: error: Selected sound system is not available. Steps to reproduce: 1) emerge -C pkgconfig 2) emerge rdesktop My build log is in attach.
Thanks for the report! I have added pkgconfig to current ebuilds DEPEND
