Thanks very much for checking! Could someone please report on
status for OSX, and corroborate my finding that it works for my
source installed GRASS on Fedora - other Linux variants and
installation mechanisms (Ubuntu etc. installed binary?? may vary.

Hi Roger, <br>
<br>
thanks for this update, great! I just checked for Ubuntu 14.04. When
running R from within a GRASS session, I can now use installed GRASS
addons. Great! initGRASS doesn't seem to work though (I never use
it, so if I am overlooking something, please let me know). See
below:<br>
