Cannot install octave packages

[matthias@…]

If I try to install octave packages (e.g. octave-strings), I get the following:

---------------------------------
sudo port install octave-strings
Password:
--->  Computing dependencies for octave-strings
--->  Staging octave-strings into destroot
Error: Target org.macports.destroot returned: error renaming "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_math_octave-strings/work/destroot/opt/local/share/octave/octave_packages": no such file or directory
Log for octave-strings is at: /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_ports_math_octave-strings/main.log
Error: Status 1 encountered during processing.
To report a bug, see <http://guide.macports.org/#project.tickets>
---------------------------------

I have no clue what's going on, but I believe something is not configured the way it should be (either with Octave itself, or with the packages).
