This probably means that Tcl wasn't installed properly

I also make sure to have these packages installed on Ubuntu

$ sudo apt-get install tk8.5 tcl8.5 tcl8.5-dev

Any luck? Having same issue.

Apt-get installs the tcl in the global namespace so your env won't have access

This suggestion fixed a similar issue for me:
options(menu.graphics=FALSE)
