Two compilation errors

[Tong <mlist4suntong@yahoo.com>]

Hi, 

I'm trying to compile DWI (a simple system to create data driven
applications, http://www.linas.org/linux/dwi/), but met with 2
compilation errors. 

1) in the dwi-gtk directory, I got the "No package 'xml2' found" error:

make[2]: Entering directory `/export/home/tong/try/dwi-0.6.1/dwi-gtk'
if /bin/sh ../libtool --mode=compile gcc -DHAVE_CONFIG_H -I. -I. -I..    -I ../app -I ../src -I ../db_drivers `pkg-config --cflags xml2 glib-2.0 gobject-2.0 gtk+-2.0 libgnomeui-2.0 libglade-2.0`  -I/usr/include/glib-2.0 -I/usr/include/gtk-2.0 -I/usr/include/libgnomeui-2.0 -I/usr/include/libxml2 -MT duifield-gtk.lo -MD -MP -MF ".deps/duifield-gtk.Tpo" -c -o duifield-gtk.lo duifield-gtk.c; \
then mv -f ".deps/duifield-gtk.Tpo" ".deps/duifield-gtk.Plo"; else rm -f ".deps/duifield-gtk.Tpo"; exit 1; fi
Package xml2 was not found in the pkg-config search path.
Perhaps you should add the directory containing `xml2.pc'
to the PKG_CONFIG_PATH environment variable
No package 'xml2' found

How can I fix this? 

Note that I'm sure I have the libxml2 libxml2-dev packages
installed. Besides, I tried to search for the "xml2.pc" from the
"Debian Package Contents Search" but didn't find any match.

2) I met the error "glibconfig.h no found" :

gcc -DHAVE_CONFIG_H -I. -I. -I.. -I ../app -I ../src -I ../db_drivers -I/usr/include/glib-2.0/include -I/usr/include/glib-2.0 -I/usr/include/gtk-2.0 -I/usr/include/libgnomeui-2.0 -I/usr/include/libxml2 -MT duifield-gtk.lo -MD -MP -MF .deps/duifield-gtk.Tpo -c duifield-gtk.c  -fPIC -DPIC -o .libs/duifield-gtk.lo
In file included from /usr/include/glib-2.0/glib/galloca.h:30,
                 from /usr/include/glib-2.0/glib.h:30,
                 from duifield-gtk.c:36:
/usr/include/glib-2.0/glib/gtypes.h:30:24: glibconfig.h: No such file or directory

This is strange, 

- the glibconfig.h file is at
  /usr/lib/glib-2.0/include/glibconfig.h:

$ dir /usr/lib/glib-2.0/include/glibconfig.h
-rw-r--r--  1 root root 5039 Aug 24 12:55 /usr/lib/glib-2.0/include/glibconfig.h

- I've include the path "/usr/lib/glib-2.0/include" on the gcc
  command line.

- shouldn't gcc find all the header files for -dev packages?

I kept getting .h not found error and was forced to search those
header files and add their paths manually. Now my configure looks
like this and it is still not enough:

configure CFLAGS='-I/usr/include/glib-2.0/include -I/usr/include/glib-2.0 -I/usr/include/gtk-2.0 -I/usr/include/libgnomeui-2.0 -I/usr/include/libxml2'

How can I fix this problem? 

Thanks

BTW, anyone knows a pre-compiled debian package for DWI?
