i modified /usr/pkgsrc/pkgtool/pkg_install/Makefile
and added this to end of the file:
CFLAGS+=-g
STRIPFLAG=

Then I rebuilt the package with make clean & make update.
then moved to /usr/pkgsrc/x11/gnome-libs and there
make clean & make update
it dumped core like it did before.
gdb pkg_create pkg_create.core

it says:

This GDB was configured as "i386--netbsdelf"...Dwarf Error: Cannot handle
DW_FORM_strp in DWARF reader.

Core was generated by `pkg_create'.
Program terminated with signal 11, Segmentation fault.

i type bt and it prints:

i hope this is what you wanted, i've never used gdb before :)
