problem starting R in Komodo with sciviews-k (Ubuntu)

[stas-g]

i have successfully installed sciviews-k and am now trying to start an R session in Komodo.
in the R -> Configure R i have 'use this application: /usr/bin/R' (with the --quiet option) which is correct as it is where R lives on my machine. then it says that this command will be used to start R:
x-terminal-emulator -e '/usr/bin/R --quiet' --args --svStartPkgs=SciViews

however, when i try to run R (with or without the --quiet option) an x terminal pops up along with a shell window with a red box in it saying:

There was an error creating the child process for this terminal
Failed to execute child process "/usr/bin/R --quiet" (No such file or directory)

and offering me two options: either to relaunch (which obviously fails) or to go to profile settings, which i did but found nothing i could alter to amend the situation.
