Installing Gtk2 on my macbook

I have had my macbook for two days, so I am new to all this. I have installed Xcode, which came as a dmg file, and that was dead simple. Now I am eager to get gtk2, and Darwinports has a very up to date version (2.12.9, which is more recent than the 2.12.8 on my up to date Fedora Core 8 linux machine). I follow the instructions to install darwinports, then do the following. I am astounded by the multitude of supporting packages. (It fetches them all from the penultimate sites, and builds them for me, not what I would have expected.) I go home and leave it running. In the morning it seems to have happily finished, with the trail of activity appended at the end of this page.

It even installs perl-5.8.8 !!

I then procede to build my gtk2 application, which goes smoothly, until I try to actually run the application, at which point I get a "cannot open display :0.0" error. This is easily fixed by removing the line which sets the display variable in my .profile file. I am told that with Leopard (Mac OSx 10.5), the DISPLAY environment variable will be magically set to some pipe in /tmp and this will just work (and in fact it does!) if you don't screw with it. In other words the advice to set DISPLAY for darwinports is just out of date information for Leopard. In fact, this seems to be really nice in that Leopard will start the X server as needed if this pipe scheme is used.

It just works, pretty cool. No need to install X11 (or even start X11).
