[FORGE] Fem-fenics installation fails

[Juan Pablo Carbajal]

With Fenics 1.3.0 installed from PPA on Ubuntu 13.10 amd64
and with
$> locate dolfin.h
/usr/include/dolfin.h

The installation in Octave gives
octave-cli-3.8.0:1> pkg -forge install fem-fenics
configure: error: dolfin required to install Msh Package
[...]
checking dolfin.h usability... no
checking dolfin.h presence... no
checking for dolfin.h... no

pkg: error running the configure script for fem-fenics.
error: called from 'configure_make' in file
/usr/local/share/octave/3.8.0/m/pkg/private/configure_make.m near line
72, column 9

I guess some environment variable should be defined. I couldn't find
help in the fem-fenics manual.

Any clues?
