cvs gnome-guile & guile-gtk do not configure

[David Pirotte]

I've checkout a completely new module today as well, to make sure, 
trying to configure I get the following error:
[I have installed pkgconfig-0.8.0]

        address@hidden:~/ftp/guile/guile-gtk 10 $ sh ./autogen.sh
        ...
        creating libtool
        loading cache ./config.cache
        checking how to run the C preprocessor... gcc -E
        checking for pkg-config... yes
        ./configure: line 2092: syntax error near unexpected token 
`GNOME_PKGCONFIG_CHECK_MODULES(GTK,'
        ./configure: line 2092: `        GNOME_PKGCONFIG_CHECK_MODULES(GTK, 
gtk+-2.0:1.3.1      gthread-2.0:1.3.1)'
        address@hidden:~/ftp/guile/guile-gtk 10 $ 


gnome-guile produces exactly the same error

thanks for some hints,
david
