 Priority:  Normal  |  Milestone:

--------------------+----------------------
 I installed Xcircuit following the page
 https://ports.macports.org/port/xcircuit/. The installation ran
 successfully,
 But when I run xcircuit in terminal, I get the below error - Can you help
 me figure out what I am running wrong?

 I tried installing tcl using MacPorts, but that says its already installed
