libgtkxmhtml.so vs. webdesigner: undefined symbols

[Paul Barnfather <plb clanger9 demon co uk>]

I have GNOME working fine, but the latest release of webdesigner
dies with unreferenced symbols in libgtkxmhtml.so:

Undefined			first referenced
 symbol  			    in file
png_set_strip_16                    /usr/local/lib/libgtkxmhtml.so
png_set_read_fn                     /usr/local/lib/libgtkxmhtml.so
inflateEnd                          /usr/local/lib/libgtkxmhtml.so
jpeg_start_output                   /usr/local/lib/libgtkxmhtml.so
png_create_read_struct              /usr/local/lib/libgtkxmhtml.so
XpmFreeXpmImage                     /usr/local/lib/libgtkxmhtml.so
etc, etc...

I am using gnome-libs-1.0.56.

ldd -R /usr/local/lib/libgtkxmhtml.so produces even more errors.
Is there something badly wrong with my build of gnome-libs?
