it's because extras are not compiled with -DPDINSTANCE.

if you remove the full 98th line of the libpd/Makefile ("bob~.o bonk~.o
choice.o fiddle~.o loop~.o lrshift~.o pique.o sigmund~.o \"),
make clean and re-make, I think the error will disappear.
I was even able to run the test_libpd with some additional hacks.

Anyway this part still needs work;
work is in progress regarding multi instance hooks (see
https://github.com/libpd/libpd/pull/282 and
https://github.com/libpd/libpd/pull/343), before the inclusion of libpd
into Pd can be fully completed.

cheers
