Hi Chris,

Yes, there's an easier way.  The main thing you want to do is to copy
config/gr_standalone.m4, config/gr_gcell.m4, and config/pkg.m4 out of the
trunk and add them to your out-of-tree config directory.  Invoke
GR_GCELL in your configure.ac and most of what you need will be set
up.  See the attached files below.

I generally use a directory structure that looks like this:

  mymodule/config               # m4 macros
  mymodule/include/mymodule     # includes that will be installed in 
PREFIX/include/mymodule
  mymodule/include/mymodule/spu # SPU specific includes that will be installed
  mymodule/lib                  # generic code
  mymodule/lib/gcell            # code that uses gcell
  mymodule/lib/gcell/spu        # SPU code used by code in lib/gcell
  mymodule/python
  mymodule/apps

lib/gcell is only built if the AM_CONDITIONAL HAVE_GCELL is true.

There's also a HAVE_GCELL value in config.h


If I get some time, I'll work up a revised out-of-tree skeleton that
includes conditionally built code that uses gcell.  In the meantime, 
I'm working on a "gcell-ized" version of FFTW :-)
