...ok, had to remove "-shared", "-lcrypt", and do:

LDSHARED = $(CXX) -undefined dynamic_lookup

...then I was able to complete the compile using:


...nifty!  The deployment target is necessary to make "-undefined  
dynamic_lookup" work:  might be able to add "-mmacosx-version- 
min=10.3" to the link line, but I haven't tested (seems like xcode  
does this for gem)...

...anyway, I added the path and such to my pd.app, relaunched, and  
got the following:

setting up Ruby-for-PureData...
gridflow.pd_darwin found itself in /Users/tigital/puredataDev/gridflow
we are using Ruby version 1.8.4
ERROR: Cannot load GridFlow-for-Ruby (gridflow.so)

...any ideas?
