octave seg fault and uninstall

[Michael D Godfrey]

John,

I am now able to do a bit more diagnosis on the problem of
recent Octave's seg faulting when using openGL.  It turns out
that the real problem was due to "leftover" libraries from earlier
installs.  This became pretty clear when I noticed that I got different results
building the current system on different machines.  But, when I
tried make uninstall on the machine that was failing, it did not fix
the problem.  So, I found that after make uninstall the following
libraries were still present (and leftover from an install on 4 October).

address@hidden lib]# ls -l octave-3.3.50+/
total 246040
-rwxr-xr-x. 1 root root    603555 2009-10-04 22:44 libcruft.so.3.3.50+
-rwxr-xr-x. 1 root root  93683423 2009-10-04 22:44 liboctave.so.3.3.50+
-rwxr-xr-x. 1 root root 157644153 2009-10-04 22:45 liboctinterp.so.3.3.50+
address@hidden lib]# pwd
/usr/local/lib
address@hidden lib]#

So, I did rm -rf /usr/local/lib/octave-3.3.50+
and then make install.  This fixed the problem.  It appears that there was
something unintended in the naming of libraries on about 4 October.
You may reasonably consider this to be too esoteric to worry about, but
a somewhat more forceful version of uninstall might make sense.
