I have been no longer using Ubunutu 12.04.
However, gcc-4.6 is rather old to compile octave.

I have forgotten the apt-get command but I have installed gcc-4.8 (gcc-4.8, 
g++-4.8 and gfortran-4.8)
Please search the way bu Google.

At configure
CC='gcc-4.8' \
CXX='g++-4.8' \
F77='gfortran-4.8' \
./configure (other option)

If you want to build with the osmesa, the osmesa on ubuntu 12.04 is too old to 
build with octave-4.0.x.

I have built the osmesa using instruction
