Installation problems

[Paolo Lorenzetti]

I've found some problems during installation of octave on a 486 with Linux 
1.1.59. Here what I've done:

-> downloaded "octave-1.1.1-2.ELF.bin.tar.gz" in my ~/tmp/octave

-> tar xvzf octave-1.1.1-2.ELF.bin.tar.gz

-> cd octave-1.1.1

-> I have executed doinstall:
   ./doinstall.sh
   ./doinstall.sh: unable to extract version number from Octave!

-> So I've tried to run octave:
   ./octave
   bash: ./octave: No such file or directory

Well I've '.' in PATH and the right access permission to octave.

What should I do ???

Please answer quickly, I need octave !

Thanks,
                                                Paolo Lorenzetti
