media-libs/mediastreamer is gone from the Portage tree despite being required by, say, net-voip/linphone-3.6.1-r1, so can't get that installed
I'm not sure what you are talking about: $ eshowkw linphone No such package "linphone"
I'll send this one where I think it makes the most sense. *** This bug has been marked as a duplicate of bug 691640 ***
