 There doesn't seem to be an xaw-dev package, only an xaw3dg-dev
 package.  If you don't have xaw3dg-dev installed, you could try
 installing that.  If you do, you could try uninstalling that. 
I don't have it; I'll now try to install it and return the 3D stuff to 
ld.so.conf.
 I don't recommend uninstalling either xaw3dg itself or the
 xaw-wrappers package; I suspect that a lot of Debian's stock X stuff
 is linked against xaw, and presumably xaw3d.  Some of it might give
 you the same headache in reverse. 
I don't think that would be a problem; I've removed the 3D stuff from
ld.so.conf, and everything still worked.  But maybe I didn't try the
right things.
