Thanks,

Using this advice and the great 'searchlib' utility
from Paul Kienzle, I was able to get this to work
under RH6.2.  The basic trick was not to link with
the libkpathsea or libreadline supplied with the
distribution, but to link with the one that comes
with octave.

So, the working version is:

cat >> stand.cc
#include <octave/oct.h>
main(){ ColumnVector dx (3); }
^D

cc -c stand.cc -I/usr/local/include/octave-2.1.31/octave/
cc stand.o -L/usr/local/lib/octave-2.1.31 -loctave -loctinterp ŠÜ
   -ldl -lcruft -lstdc++ -lg2c -ltermcap ŠÜ
   -L/usr/src/octave-2.1.31/kpathsea -lkpathsea ŠÜ
   -L/usr/src/octave-2.1.31/readline -lreadline

export LD_LIBRARY_PATH=/usr/local/lib/octave-2.1.31
./a.out
strip ./a.out 
ls -l ./a.out 
-rwxrwxr-x    1 andy     andy       172896 Oct 16 22:44 ./a.out



Meanwhile, enquiring minds want to know: Is
octave putting extra functionality into kpathsea
and readline, or is Redhat leaving functionality
out?

Thanks for all the help.
