That's what I saw too.  The standalone tests worked OK.

It could be that we're generating 64-bit .so's and that python is
compiled as a 32-bit app.

Try 

  $ file /usr/bin/python

  $ file /usr/local/lib/libgnuradio-core.so


If that's the case, then compiling our stuff in 32-bit mode would be
the next experiment.  I think you can get that with

  $ CXXFLAGS="-mno-powerpc64" ./configure

Note that CXXFLAGS is in front of ./configure


Any PPC experts out there?  Besides the difference in address space,
is there any compelling advantage to using the PPC in 64-bit mode vs
32-bit mode?  On the X86-64 it's a big win to be in 64-bit mode since
you get twice as many registers.  I know that this isn't the case on
the PPC since you've always got 32 regs.
