Re: [Discuss-gnuradio] error compiling audio_ osx_sink on OS X 10.6.2 "audio_osx_sink .cc:101: error: ‘ComponentDescription’ was not declared in this scope "

You need to modify 'bootstrap' to use 'glibtoolize' instead of  
'libtoolize'.

The list archives are your friend:  http://lists.gnu.org/archive/html/discuss-gnuradio/ 
  , and then search for the term ... e.g. "libtoolize" top 2 hits are  
about building under OSX, and the need to modify bootstrap as per the  
above.  Hopefully this simple change will take care of your problem &  
get you moving with GNU Radio on OSX.

Please do note that, at this time, the WX Python interface is not 64- 
bit compatible so you'll need to compile as 32-bit for now.  WX itself  
(wxWidgets) release 2.9.0 is out & is supposed to be fully 32/64-bit  
on OSX now, but the Python interface is not yet.  There was some  
discussion on this topic recently ... search for it in the archives if  
necessary when you get to that point. - MLD
