    Joao> small window? what do you mean? not a X plplot window?!

This gives a window with the window name 'Figure 0' with the geometrie
'0: 450x400+386+35'.

And this gives a window wich looks the same like the X11-Window if one
execute for example 'x01c' compiled from 'x01c.c' and using 'xwin' as
output device.

Yes it is before:  I do path("plplot_octave_path", LOADPATH);
And a new octave session.
By the way, in my example above I missed the call to 'plenv', sorry.
The correct example:

octave:39> plplot_stub;
octave:40> pldevice="xwin";plsdev(pldevice);plinit
octave:41> plenv(1,10,-1,1,0,0);
octave:42> plmtex("t",1.0,0.5,0.5, "#gS#u5#d#b#dn=1#u");

octave:46> plend

I solved it the other way:
I used the default prefix of plplot and then I linked the stuff to the
usual places '/usr/local/lib', '/usr/local/include', ...
