    _______________________________________________________

Details:

In package installation, a lookfor cache is generated for binary functions
only if the package is installed by a non-root user, not if it's installed
system-wide by root.

The reason is that pkg/private/generate_loofor_cache.m generates caches only
under directory 'desc.dir', which in the install-as-root case does not contain
the directory with the binary functions.

(You can verify the bug by checking that 'doc-cache' is lacking in the
directories of binary function of system-wide installed packages.)

Fix:

in pkg/private/generate_loofor_cache.m, after the line:


  dirs = strtrim (ostrsplit (genpath (desc.dir), pathsep ()));

, insert the following:

  if (! strcmp (desc.dir, desc.archprefix))
    adir = fullfile (desc.archprefix, getarch ());
    dirs2 = strtrim (ostrsplit (genpath (adir), pathsep ()));
    dirs = cat (2, dirs, dirs2);
  endif


I don't think that I need to make an own changeset for such a bit, feel free
to apply it.

Olaf
