I have a new Imac running yosemite. I downloaded Synfig and I did these steps
On this side you’ll find how to install macport; macports.org/install.php
there is a link to download the install file for “Leopard”, (os 10.5), on the same side.
It will take a long time to make the install complete so be patient 
When the “macport” install is ready you have to run this commands in the “terminal”:
- sudo port -v selfupdate
this command will se to that macport and all installed will be up to date, it will take a while, when it’s ready then: - sudo port install synfigstudio
this will also take a long time since all dependencies will be installed.
When this is ready you open terminal and write “synfigstudio” and hit return and Synfig will start.
and when I typed in synfigstudio this is the error I get.
synfig studio – starting up application…
Dynamic session lookup supported but failed: launchd did not provide a socket path, verify that org.freedesktop.dbus-session.plist is loaded!
(synfigstudio:22493): Gtk-WARNING **: cannot open display:
If Anyone can give me some advice I would greatly appreciate it as I have scoured over everything I can find and can’t figure out how to make it run on Yosemite
Thanks!!!
