[PD] Gem on ibook G4

[vincent rioux]

hi,

i recently found that i could not get a Gem release with pix_mean_color 
included, to work on ibook G4 (os10.4.2) machines.
for example the latest version of Hans C.S. or Tigital gives the 
following error :
symbol not found : _glFramebufferRenderbufferEXT

??
