How can I configure my OpenOffice and Xserver to speak the same language?

Dear List.

I am running NetBSD 5.1 (GENERIC) (amd64) and I have built packages
with sources from 2010Q4.

I have problems with OpenOffice3.  I try to start it with:
    pluto:dino {101} soffice
    I18N: Operating system doesn't support locale "en_US"
OpenOffice starts, however,  and it lets me select the text part.

The Xserver gives the following error message:
    The XKEYBOARD keymap compiler (xkbcomp) reports:
    > Warning:          Duplicate shape name ""
    >                   Using last definition
The last two lines are repeated some 20 times, before the Xserver
says:
    Errors from xkbcomp are not fatal to the X server

In OpenOffice, I can type all letters on my Danish keyboard
(inclusive the three special Danish/Norwegian letters).  But several
of the special characters (like ~ ` ') do not function.  I cannot
even construct the Western European letters with those and other
diacriticals.

I can type those characters in an Xterminal with e.g. ~<space>, and
construct Western European (ISO 8859-1) letters with  diacriticals
like e.g.  Spanish ñ.  Afterwards I can copy-paste them into my
OpenOffice document.

My "xorg.conf" contains the keyboard definitions:
    Section "InputDevice"
            Identifier  "Keyboard0"
            Driver      "kbd"
            Option "XkbRules"       "xorg"
            Option "XkbModel"       "pc105"
            Option "XkbLayout"      "dk"
    EndSection

I have forested through several {M,m}akefiles and *mk* files and man
pages.  Can anybody please give me a handle where to do what.
