[R-SIG-Mac] Error loading tcltk library

[Ivan Alves]

Dear all,

The latest leopard snapshot of R 2.8.1 seems to have a problem loading  
the tcltk package, and found no related entries in  
gmane.gmane.comp.lang.r.mac.  It appears to be a broken link. Any  
suggestions on how to fix it? Many thanks in advance.

Best regards,
Ivan
