I did what ought to be effectively the same thing, except instead of
deleting the files, I just moved them all to /tmp so I can recover 
them easily later on.  So when I started the build, there was nothing
left under /usr/local matching the regexp 'octave*'.  I then ran

    make distclean
    make
    make check
    make install

all as root. Behavior same as before.

Anyone else out there running RH7.3 (or similar-vintage gnu/linuces)
that could check to see whether this is happening for them? Here's the
minimal example:

    1>   foo = rand(10);
    2>   save("-binary", "bar", "foo")
    3>   load bar
    error: load: trouble reading binary file `bar'


I admit that this seems like it's gotta be a build problem on my
part, but I sure can't find it.  More or less a vanilla build done
in a vanilla way. The only config options were --enabled-shared,
--enable-dl, and --enable-lite-kernel.

I did that when I first came across the problem, but everything looked
right.  Here's the full ldd from the version I just built as per the above::

  liboctinterp.so => /usr/local/lib/octave-2.1.57/liboctinterp.so (0x40014000)
  liboctave.so => /usr/local/lib/octave-2.1.57/liboctave.so (0x40778000)
  libcruft.so => /usr/local/lib/octave-2.1.57/libcruft.so (0x40ca9000)
  liblapack.so.3 => /usr/lib/liblapack.so.3 (0x40d22000)
  libblas.so.3 => /usr/lib/libblas.so.3 (0x4115e000)
  libreadline.so.4 => /usr/lib/libreadline.so.4 (0x411a8000)
  libncurses.so.5 => /usr/lib/libncurses.so.5 (0x411ce000)
  libdl.so.2 => /lib/libdl.so.2 (0x4120d000)
