Gnucash-gdb (which does the same setup as gnucash-launcher, then exec gdb gnucash instead of exec gnucash) doesn't
seem to work right for me. I generally start gnucash-launcher, pause it with ctrl-z, get the process number (I use ps | grep gnucash, but you could use Activity Montitor if you'd rather), start gdb, and attach the running gnucash process. I think, but have never been able to prove, that the trouble is caused by having to start dbus in the shell script.

I also find that it's necessary to link the dSYM directories (which are built in the individual .libs directories) to be next to their installed libraries for gdb to be able to find the symbols.

Aside from dbus, libtool gets in the way. It's a bit of a hack on OSX -- and should be unnecessary -- but it's hardwired into the autotools build system. Libtool is where all those .la? files come from.

Good point about rm -f gnucash, except that rm -fd will fail, too, because the gnucash directories have a symlink in them. The needed command would be "rm -rf".
Not really a big deal though. The symlinks don't take up much space.
