libart header compile error

[<ashalper cox net>]

When compiling current CVS on Debian unstable, I'm winding up with the following compile error:

gcc -DHAVE_CONFIG_H -I. -I. -I.. -I../intl -I/usr/include/libxml2 -I/usr/include/gtk-2.0 -I/usr/lib/gtk-2.0/include -I/usr/include/atk-1.0 -I/usr/include/pango-1.0 -I/usr/include/freetype2 -I/usr/X11R6/include -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/libxml2 -I/usr/include/libart-2.0 -DDIA_SHEETDIR=\"/usr/local/share/dia/sheets\" -DLIBDIR=\"/usr/local/lib\" -DDATADIR=\"/usr/local/share/dia\" -I/usr/include/libxml2 -g -O2 -Wall -Wunused -Wmissing-prototypes -Wmissing-declarations -finline-functions -fstrict-aliasing -Wp,-MD,.deps/dialibartrenderer.pp -c dialibartrenderer.c  -fPIC -DPIC -DPIC -o dialibartrenderer.o

My libart-dev packages are:

ii  libart-2.0-dev 2.3.14-1       Library of functions for 2D graphics - devel
ii  libart-dev     1.4.2-14       The GNOME canvas widget - development files

I tried uninstalling the libart-2.0-dev package, but got a different error message.  Is there a work-around?  './configure --disable-libart' didn't seem to help either.

Thanks,
Andy
