$ ldd src/xemacs
libXaw.so.6 => /usr/X11R6/lib/Xaw3d/libXaw.so.6 (0x40018000)
This is the /wonderful/ Debian thing. At compile time, with flat Xaw, we
pick up /usr/X11R6/lib/libXaw.* -- but at runtime the ld.so.conf puts
the Xam3d library as 'libXaw.so' in the path first.
This can't be found through any method short of dynamic-linking of an
executable at configure time and looking in the output on STDERR for the
cursed `consider relinking' thing.
The quick fix[1] is to edit /etc/ld.so.conf and move the entry for
/usr/X11R6/lib/ before the entry for /usr/X11R6/lib/Xaw3d/.
That will pick up the correct flat Athena.
Building with `--with-athena=3d' will also work.
I don't know if we /can/ do anything much about the issue otherwise.
It's not actually fixable easily (thanks, Debian) as far as I can see.
LD_PRELOADing the correct Athena library would also work....
