I forget what the answer was for 0.10.2, but the current version is
0.10.3 - and, in that version, you'd add it to the "DISSECTOR_SRC" macro
in the "epan/Makefile.common" file (and put "../" in front of the
dissector name, as is done for the names already there).

Those are both due to the same change - the Ethereal and Tethereal
executables no longer contain the dissectors or the libethereal or
libwiretap code on most platforms; they're now in shared libraries.  We
use libtool on UN*X to make that work; one consequence is that
"ethereal" and "tethereal" are shell scripts that run the actual
binaries with the appropriate environment-variable settings so that they
find the shared libraries in the build directory.

This means that, instead of doing

	gdb ethereal

or

	gdb tethereal

you instead do

	./libtool gdb ethereal

or

	./libtool gdb tethereal
