I think this is a SWIG issue.  I'm using version 1.3.37, which for  
some reason requires the addition of "-outdir $(builddir)" in order to  
work correctly.  Without this addition, one file is written to $ 
(srcdir) and the other to $(builddir) [which, when doing distcheck,  
will error out because $(srcdir) is not writable].

I think the correct solution is to add this change to the  
Makefile.common variable "SWIGPYTHONFLAGS" ... but even with that some  
of the gr-foo components need to be updated to handle this correctly  
(e.g., gr-audio-osx, gr-atsc, gr-audio-windows, gr-comedi, gr-video- 
sdl, ... probably others).

I'm happy to make these changes into a test branch to verify  
compatibility with older SWIG version(s) ... that is, if this is the  
correct way to go.  Thoughts?  Comments?  Suggestions? - MLD
