Compiling problems

I was trying to build the gnome-libs to a different subdirectory, and I'm getting the following error:

/bin/sh ../libtool --mode=link pgcc  -O6 -mpentium -Wall -Wno-unused   -o htmltest  test.o ../gtk-xmhtml/libgtkxmhtml.la        -lXpm -ljpeg -lpng -lz -lz -lSM -lICE -L/usr/X11R6/lib -L/usr/X11/lib -lgtk -lgdk -rdynamic -lgmodule -lglib -ldl -lXext -lX11 -lm  -lz -lm

What am I missing?
