installing Octave 4.0.1

[Steph Bredenhann]

I am install Octave 4.0.1 0n a Lenovo W520 laptop running Ubuntu 15.10, 
./configure and make was successful, but sudo make install ended with:

  GEN      .DOCSTRINGS
Unable to parse dldfcn/__init_fltk__.df at line 4
Makefile:8856: recipe for target '.DOCSTRINGS' failed
make[3]: *** [.DOCSTRINGS] Error 25
make[3]: Leaving directory '/tmp/octave-4.0.1/libinterp'
Makefile:3712: recipe for target 'all' failed
make[2]: *** [all] Error 2

make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory '/tmp/octave-4.0.1'
Makefile:1995: recipe for target 'all' failed
make: *** [all] Error 2

I have installed all dependencies as per 
http://wiki.octave.org/Octave_for_Debian_systems

I've done a similar install on my PC successfully.

Any advice

Regards Steph
