"We" made numerous Darwin-specific changes to the GNU Radio GIT master  
recently to resolve 10.6 and 64-bit compiling issues (mostly debugging  
printouts, by moving "fprintf(stderr,...)" to "std::cerr << ...").   
Hence the GNU Radio -GIT master- should now be compatible with OSX  
10.4, 10.5, or 10.6 as 32-bit or 64-bit.  I have successfully tested  
GNU Radio in 32-bit on each of these (Intel only, but that shouldn't  
make a difference), and in 64-bit on 10.6, using MacPorts for all  
installable dependencies (NB for 10.6: see the last real paragraph  
below).

I believe that Ed was asking specifically about the 3.2.2 release.   
GNU Radio -release 3.2.2- does not have these recent GIT master  
changes for both 10.6 and 64-bit OSX, but most of 3.2.2 should compile  
as 32-bit since it was originally (inadvertently) designed to compile  
as 32-bit -- only gr-audio-osx needs changes to compile under 10.6  
because Apple changed the CoreAudio API.  To the best of my knowledge,  
GNU Radio was never compiled as 64-bit under 10.5 (or 10.4,if that's  
possible) ... hence it's only with the move to 10.6 that these bit- 
width issues came up -- and were promptly addressed.

Thus, to summarize, assuming we're talking about the GNU Radio GIT  
master: The issues are not with GNU Radio.

The issues w/r.t. 10.6 &/or 64-bit are instead with the dependencies  
wxWidgets and wxPython: Up through the 2.8.10 series, the WX* codebase  
was 32-bit compatible on OSX but would fail when compiled as 64-bit  
(and, OSX won't allow one to mix & match 32- and 64-bit libraries and  
applications).  Starting with WX* 2.9.0, the codebase will be both 32- 
bit and 64-bit compatible on OSX 10.5 or 10.6 < http://wxwidgets.org/  
>; wxWidgets 2.9.0 has been released, but wxPython has yet to catch  
up before "we" can test them out with GNU Radio (via MacPorts or  
otherwise)

I hope this note clarifies your issues; if not, ask more. - MLD
