>From the gcc manpage:

-g  Produce debugging information in the operating system's native format
(stabs, COFF, XCOFF, or DWARF 2).  GDB can work with this debugging
information.

So add -g to your CFLAGS.  (Set CFLAGS="-g" plus whatever other CFLAGS you
use before compiling.)  Note that various optimizations can make debugging
difficult, of course.  See the manpage for additional -g<otherstuff> flags.

Finally (and in general), note that symbols may be stripped by the
build/make script. I'm not sure if pan's does or not, but at the
./configure step, you can try ./configure --help and see what it spits
out.  It's  likely you can add a debug option there that will take care of
the gcc -g as well as any stripping.
