newbie: building gnumeric

[Bryan <bryan arbores ca>]

I have a stock RedHat 9 installation and am trying to compile gnumeric 
1.2.2.

The configure command dies after saying:

> checking for pkg-config... /usr/bin/pkg-config
> checking for
>                 libbonobo-2.0 >= 2.2.0
>                 libbonoboui-2.0 >= 2.2.0
>                 libgsf-gnome-1 >= 1.8.2
>                 ... Package libbonobo-2.0 was not found in the 
> pkg-config search path.
> Perhaps you should add the directory containing `libbonobo-2.0.pc'
> to the PKG_CONFIG_PATH environment variable
> No package 'libbonobo-2.0' found

After some hunting around on the web, I found out about /usr/lib/pkgconfig 
and /usr/local/lib/pkgconfig. These dirs contain some .pc files, but not 
the ones gnumeric seems to be looking for.

Could someone point to a reference or something that explains how to 
install and configure this pkg-config stuff?

Thanks!
