I think skipping 'make install' alltogether and just running things  
directly is much easier for dev work.  Something like this:

cd pd-double/pd
./autogen.sh && ./configure --enable-double-precision && make
cd extra
ln -s ../../externals/creb
cd ..
./src/pd

Now you have a way to run pd-double's Pd using the creb you are  
working on.  Then to build creb after mods, just do:

cd pd-double/externals
make creb
