compile problems

[Don Epand]

Hello,
I am a octave newbe, but not to linux. Last froday evening I
compied octave 2.0.13 with no problems on a redhat-5.0 system.
Yesterday I upgraded my system to redhat-5.1 and tried to compile.
I got tons of warnings and compilation failed with undefined
NPOS. The warnings were all similar to below:
making oct-conf.h from oct-conf.h.in
oct-conf.h is unchanged
c++ -c  -I. -I.. -I../liboctave -I../src -I../libcruft/misc   -DHAVE_CONFIG_H

And the error:
defaults.cc: In function `class

_alloc_template<true,0> > subst_octave_home(const class 
basic_string<char,string_cha

make[1]: Leaving directory `/home/depand/octave/octave-2.0.13'
make: *** [all] Error 2                      

I also am trying to install octave on some remote systems at
Tennessee State University which are running redhat-4.1 and
get errors there, which I have not logged.
My question is is there a fix for the redhat-5.1 errors and
is there an older compiled version around for redhat-4.1.

I got involved in all this because I could not get multiplot
function to work. Just discovered the README.gnuplot on the
ftp site today, and my version of gnuplot is 3.5. The README.gnuplot
was not included in the source I got.

Any help would be appreciated.
thanks
