Ok, since I'm currently installing into my home directory, I get

   $ ls -lp lib/
   total 336

If I understand you correctly, I could replace "~/lib/libsane.so.1.0.29"
with a symbolic link to  "~/lib/sane/libsane-pixma.so.1.0.29",  and that
would just work.   Hmm ... isn't that something  "make install" could do
on its own,  if just a single backend is configured?   I do not have any
numbers regarding whether or not people  configuring only a single back-
end are the extreme exception, but it could optimize their installation.

Sincerely,
  Rainer
