Problems with libg++ installing octave 1.1.1

[Mario Storti]

Installing  octave 1.1.1 from the Slackware 3.0 binary distribution
on Linux 1.2.13.

When I run the script '. ./doinstall.sh' I obtain the following message

spider:/usr/lib/octave-1.1.1# . ./doinstall.sh 
doinstall.sh: unable to extract version number from Octave!

This comes from the following line in the script:

version=`./octave -v 2>/dev/null | awk '/version/ { print $NF }'`

and I then tried to run directly the octave binary. When I do this it
complains about not finding the libg++ library:

spider:/usr/lib/octave-1.1.1# octave
octave: can't load library 'libg++.so.27'
spider:/usr/lib/octave-1.1.1# 

I have libg++ in /usr/lib:

  lrwxrwxrwx   1 root     root           15 Oct  5 20:01 libg++.so.2 -> 
libg++.so.2.7.0

Note that the message points to 'libg++.so.27', so that I guess that
there is a dot missing in between the 2 and the 7. I don't know if
this is an error in the message itself or it is at the origin of the
problem.
