Thanks Olaf for your help.
Indeed it was a stupid permission problem, the files in the package directory 
were in 611, I put them in 755 and they began to work. For some optimization 
functions I tested it was OK, for other I got new error that I will sort and 
try to understand before eventually going back here.

I don't think that there is a version issue between Octave and the binary 
function of the Octave packages since I installed everything through the 
package manager of my distribution (Linux Mint) and did not added or upgraded 
packets through Octave interface.
