[PD] [GEM] [OSX] compile

[i]

HI,

Good to see action in gemland :)

was wondering if anybody, managed to compile
any of the gem versions to run on pd(os x) ?
If yes could you point me in the right direction, please...
Any info on other image (generation/manipulation/analasis/etc)
pd externals that would run on pd os x, also welcome.

so far i've found sonogram.

How feasable/hard would it be to incorporate gstreamer.net elements in 
pd ?

Thanks
