can't build it

[Dave Cottingham <dc at cobi dot gsfc dot nasa dot gov>]

I'm trying to build guile-gtk-0.19, and the make dies with:

gcc -g -O2 -o .libs/guile-gtk-1.2 main.o .libs/libguilegtk-1.2.so -L/usr/lib -L/usr/X11R6/lib -lgtk -lgdk -lgmodule -lglib -ldl -lXext -lX11 -lm -lm -L/usr/local/lib -lguile -lm -L/usr/lib -L/usr/X11R6/lib -lgtk -lgdk -rdynamic -lgmodule -lglib -ldl -lXext -lX11 -lm -lm -Wl,--export-dynamic -Wl,--rpath -Wl,/usr/local/lib
.libs/libguilegtk-1.2.so: undefined reference to `scm_master_freelist'
/usr/lib/libguile.so: undefined reference to `qt_abort'
/usr/lib/libguile.so: undefined reference to `qt_error'
/usr/lib/libguile.so: undefined reference to `qt_block'
collect2: ld returned 1 exit status
make: *** [guile-gtk-1.2] Error 1

I am at a loss.  Can anyone sell me a clue?

This is on a Slackware 7.1 system, which comes with gtk-1.2, on which I've
installed guile-1.4.

Thanks in advance,
Dave Cottingham
