spurious load_path warnings when octave is started at Unix root directory

[Alexander Mamonov]

I'm sorry, this is my first time I write to Octave lists, so I'm not
familiar with the procedure.

Initially I thought that it might be that the problem is package-related.
There are three packages on my system that use the
/usr/lib/octave/site/oct/api-v32/i486-pc-linux-gnu/ directory.
These are: octave-sp, octave-plplot, and octaviz.
The first two have one file each
/usr/lib/octave/site/oct/api-v32/i486-pc-linux-gnu/sp.oct
and
/usr/lib/octave/site/oct/api-v32/i486-pc-linux-gnu/plplot_octave.oct
Octaviz has its own subdirectory with many .oct files
/usr/lib/octave/site/oct/api-v32/i486-pc-linux-gnu/octaviz
But if I uninstall all three of the above packages I get the same kind of
warning under the same conditions about the directory
./usr/share/octave/3.0.2/site/m
which again has a relative path instead of an absolute one.

Thank you,
Alex
