I have a source based linux distro. After having the mentioned problems with 
the self compiled source tarball of octave-2.1.73, I have installed binary 
packages of octave-2.1.73 on two other platforms. I have installed the binary 
packages on Ubuntu 6.10 and on cygwin. On both systems I did not have the 
problems. When I typed there "help inv" for example, I got the following output:

octave:1> help inv
inv is the dynamically-linked function from the file
/usr/lib/octave/2.1.73/oct/i686-pc-cygwin/inv.oct

That's the reason why I was expecting to find the .oct files in 
/usr/lib/octave/.

I have had the idea of specifying --libexecdir after typing "./configure 
--help" on my source distro. And that has solved my problem.

I understand what you mean, but after my originally build without using 
libexecdir but only "--prefix=/usr" I definitely did not have "/usr/libexec" or 
"/usr/lib/octave" or any other folder with the *.oct-files. I have searched my 
whole file system for the *.oct-files. There is a significant difference 
between "should be" and "is".

So this seems to be a bug in the configure script.

I hope now you have all the information you need.

Bye, Hakan
