ld.so.conf is a Linux-thingie, it's not used on the Hurd.  The real solution
is to use DT_RUNPATH (not RPATH!) when linking the executable, but this will
have to wait for the next major binutils version.  The reason it works for
you is thta you have LD_LIBRARY_PATH set, I would guess (like in
/etc/profile)

The reason it doesn't work with xdm is that this program ignores the
LD_LIBRARY_PATH env variable for security reasons. You can configure this,
though.  I forgot the details but somewhere in /etc/X11/xdm you can tell it
to not ignore the value, or even set it to some fixed value.

Dunno right now, but any difference from how it is handled on Linux would
show up in the X Manifest check when building the packages.  Try the above
first.
