There are no core Lazarus developers that still use the gtk1 interface. The information below may be outdated.

78-====If you decide not to use Fink or if your Fink installation is customized==== If you install `gdk-pixbuf`, `gtk`, and `glib` libraries not using Fink, or if your Fink installation is customized to install under other than `/sw` directory, then make sure that the environment variable `DYLD_LIBRARY_PATH` point to where the libraries are. For instance, it you use [MacPorts](http://www.macports.org/), the command below should do the trick:
