[igraph] Error when loading the tkcl interface

[Silvia SM]

Hello,

Maybe someone can help me.  I just switch to Mac, and I'm trying to use the 
"tkplot" function, but I get this error and message when the program tries to 
load the tcl/tk interface, and I cannot continue working, I have the XQuartz 
2.7.4 (xorg-server 1.13.0), and the tcltk interface and additions on my package 
manager list.  I'm I missing something?
