As Slackware user I am very acutely aware about dependencies.
Now, I used to build linphone many years ago, but I think it broke after update to Slackware 15.0.
I tried version from
slackbuilds.org but it was not working for me, missing downloads.
Now there is yet another version of Linphone-desktop slackbuild for version 5 and, oh, list of dependencies probably even longer than ours!
I think I will continue to type things on keyboard as before ... for now.
