You could modify the code in Geomview/src/bin/geomview/x11/gvevent.c
but before you try doing that, consider this: MacX provides a way of
doing all three mouse buttons using arrow keys and mouse clicks. By
default it is configured to do the following:

Mouse click = X left mouse click
Left Arrow Key = X middle mouse click
Right Arrow Key = X right mouse click

So, pressing the left arrow key while dragging, for instance, will do
the desired rotation around the Z axis and picking can be accomplish by
pressing the right arrow key twice quickly (doubleclick) while pointing to
the thing you want to pick. Also, these key to mouseclick mappings can
be customized using the Edit->Misc Preferences menu option.

We've got Geomview working through MacX here as well and it does great!
