[R-SIG-Mac] Problems with packages that require Gtk2

[John Maindonald]

Has anyone been able to get packages that rely on Gtk2 to run under  
Leopard?

I have experimented with the playwith package, as depending on a small  
number of packages additional to Gtk2.   I can pretty consistently  
generate a bus error by attaching playwith, then printing a lattice  
object.  Note that I have not run any functions from the playwith  
package.

The same may happen if I attach all the packages on which playwith  
depends (but not playwith itself), but the bus error does not appear  
with the same consistency.

Here is a transcript on a session:
