Unfortunately the io package (currently version 1.0.13 in octave-forge) has
csvread.m, csvwrite.m and dlmwrite.m included while these already have been
implemented in core octave since version ? 3.2.3 ?
I fixed this lately in octave-forge svn but too late for the io-1.0.13 pkg.

So, dive into /usr/share/octave/packages/io-1.0.13 and wipe these files to
get access to the core octave versions which -I suppose- work better (I'd be
surprised if they are worse).
