Try creating a symlink called libgd.so pointing to
/usr/lib/libgd.so.1. The symlink can be in any directory, but that
directory must be added to LD_LIBRARY_PATH. Note that the GRASS
startup automatically adds $GISBASE/lib to LD_LIBRARY_PATH, so:

	ln -s /usr/lib/libgd.so.1 $GISBASE/lib/libgd.so

should suffice.

HOWEVER: the fact that driver/PNG has a dependency upon "libgd.so"
rather than libgd.so.1 leads me to suspect that it may have been built
using GD 2.0.x (the lack of a version in the library's "soname" is a
known problem with the Makefile for GD 2.0.x).

If this is the case, then the above won't work (you will get
"undefined symbol" errors), and you will have to either install GD
2.0.x or recompile the PNG driver from source.
