I'm confused!

Michael, can you help me understand what the problems are, and what,
if anything, we can do on the GNU Radio side to resolve them?  It
sounds like some of these problems may have more to do with
external dependencies than with GNU Radio itself.

The guts of GNU Radio definitely run on x86 and x86-64, so I'm not
sure what the "64-bit issue" is on OS/X.  Last I checked, we ran on 
64-bit PPC on Fedora too.

Thanks!
Eric
