Well, none of these worked:

Exec ["pkexec", Application.Path &/ "vcpufreq-gui.gambas"] With ["DISPLAY=" & Env["DISPLAY"],
"XAUTHORITY=" & Env["XAUTHORITY"]] Wait

'Exec ["pkexec", "env", "DISPLAY=" & Env["DISPLAY"], "XAUTHORITY=" & Env["XAUTHORITY"],
Application.Path &/ "vcpufreq-gui.gambas"] Wait

BTW, the wiki says "The first element in the list/array is the name of the command, and the other elements are the commands parameters (if any)", so I wouldn't expect the second variant to work.

Maybe I should try Shell?
