Question on building gimp dep. libgnomeui

Hi,

I want to upgrade Gimp from 2.2.13 to 2.2.17. The build stop with this:

> => Required installed package libgnomeui>=2.18.1nb1: NOT found
> => Verifying reinstall for ../../devel/libgnomeui
> ERROR: [depends.mk] A package matching ``libgnomeui>=2.18.1nb1'' should
> ERROR:     be installed, but one cannot be found.  Perhaps there is a

> make: stopped in /usr/pkgsrc/graphics/librsvg2
> *** Error code 1

> make: stopped in /usr/pkgsrc/graphics/gimp
> bash-3.2# 

So I try to build libgnomeui in /usr/pkgsrc/devel/libgnomeui and get this:

> WARNING: Package version libgnomeui-2.18.1 in /usr/pkgsrc/devel/libgnomeui/work
> WARNING: Current version libgnomeui-2.18.1nb1 in devel/libgnomeui

So how do I go on?

Thanks for helping.
