This is a known problem with the linking order. It seems, that the gtk2 needs a special linking order. But there is no nice option to tell the compiler. 
You can use the script examples/gtk+/demo/compile_with_fpc_under_linux.sh, which compiles and links manually. For example:
cd examples/gtk+/demo/
./compile_with_fpc_under_linux.sh gtk_demo.pas

You can use this script to compile any example.

Meanwhile we are searching for a better solution.

I suggest to upgrade. The beta contains some errors.
