This is what I get:

ldd /usr/local/bin/octave
	liboctinterp.so.2.1.31 => /usr/local/lib/octave-2.1.31/liboctinterp.so.2.1.31 (0x40015000)
	liboctave.so.2.1.31 => /usr/local/lib/octave-2.1.31/liboctave.so.2.1.31 (0x401d8000)
	libcruft.so.2.1.31 => /usr/local/lib/octave-2.1.31/libcruft.so.2.1.31 (0x402ed000)
	libncurses.so.4 => /usr/lib/libncurses.so.4 (0x40339000)
	libdl.so.2 => /lib/libdl.so.2 (0x4037c000)
	libz.so.1 => /usr/lib/libz.so.1 (0x40380000)
	libm.so.6 => /lib/libm.so.6 (0x4038f000)
	libstdc++-libc6.1-1.so.2 => /usr/lib/libstdc++-libc6.1-1.so.2 (0x403ac000)
	libc.so.6 => /lib/libc.so.6 (0x403ee000)
	/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

Do I have to upgrade something to make it work?

Thanks,

Stef.
