modular-xorg-server vs xsrc clients+libraries

[Geert Hendrickx <ghen%telenet.be@localhost>]

Hi,

I'm trying to install pkgsrc/x11/modular-xorg-server on my system which
currently uses NetBSD xsrc/ for the X server, libraries and clients.

Now modular-xorg-server wants to install x11/libXfixes which conflicts
with the already installed x11/Xfixes package.  The latter is a
dependecy of gtk2 and thus from a pletora of other packages on my
system.

What's the difference between both packages, and can I continue to
install modular-xorg-server on my system without rebuilding all my
packages?
