hello list.

i'm running ~amd64 on an intel i7. after syncing and updating world, i'm
having some problems:


acroread does not start, failing thus:

(acroread:31925): Gtk-WARNING **:
/usr/lib64/gtk-2.0/2.10.0/engines/libxfce.so: wrong ELF class: ELFCLASS64


also, trying to upgrade lilypond, compilation fails thus:

/usr/lib64/libz.so: invalid ELF header
Could not find the zlib library which is needed to understand WOFF


google returned many hits, but i couldn't find anything helpful in my
case. any hints?

best,


lj
