Well, the plugin has to be installed along with GDAL. So
probably root permissions are needed.

OK - a couple of tests:

- which GDAL version are you using? The search patch changed.
  If you have an "older" GDAL, try to move the plugin to
  /usr/local/lib/ (where libgdal.so stays)

- if this works, congrats (keep in mind that /usr/[local/]lib/gdalplugins
  is the new home

- if this doesn't work, move the gdal_GRASS.so back to
  /usr/local/lib/gdalplugins/

- then
  ldd /usr/local/lib/gdalplugins/gdal_GRASS.so  | grep grass
  
  Does it find the GRASS libraries? If not, 
   - either add their path to /etc/ld.so.conf
   - or link the GRASS libs into /usr/local/lib (this is what I do)
     Positive side-effect: also QGIS is happy

Hope this helps
