problem compiling sawfish-1.2-gtk1

[bryan ak net]

I'm trying to compile sawfish-1.2-gtk1 on my Slackware Linux box.
(1.3 won't work because I don't have GTK2.)  The ./configure went
fine, but make bombs with this error:

/usr/local/libexec/rep/i586-pc-linux-gnu/libtool --mode=link gcc -export-dynamic  \
  -o sawfish colors.o cursors.o display.o events.o fonts.o frames.o functions.o images.o keys.o main.o multihead.o pixmap-cache.o property-cache.o server.o session.o stacking-list.o windows.o  -L/usr/local/lib -Wl,--rpath -Wl,/usr/local/lib -lrep  -ldl  -lcrypt -lgmp -lm \
  -L/usr/lib -lImlib -ljpeg -ltiff -lungif -lpng -lz -lm -lXext -L/usr/X11R6/lib -lSM -lICE -lXext -lX11 -lSM -lICE -lX11  -L/usr/X11R6/lib  -lXinerama -lXft -lXrender -lXext -lnsl
libtool: link: cannot find the library `/usr/lib/libgmp.la'
make[1]: *** [sawfish] Error 1

Here's where the relevant libraries are on my machine:

-rw-r--r--   2694408 Jun 25  2002 /usr/local/lib/libgmp.a
-rwxr-xr-x       693 Jun 25  2002 /usr/local/lib/libgmp.la
lrwxrwxrwx        15 Feb 22  2003 /usr/local/lib/libgmp.so -> libgmp.so.3.3.0
lrwxrwxrwx        15 Feb 22  2003 /usr/local/lib/libgmp.so.3 -> libgmp.so.3.3.0
-rwxr-xr-x    696157 Jun 25  2002 /usr/local/lib/libgmp.so.3.3.0

The error message makes no sense to me, because -L/usr/local/lib
is clearly visible on the command line.  Can someone explain why
the library is not being found?
Thanks for any help.
