openSUSE: OpenOffice 3 presenter screen extension

We have been hearing and reading about the cool new presenter screen extension for OpenOffice 3 Impress.
This would result in impress displaying the presentation fullscreen on a projector, with the current and next slides plus notes on your laptop screen. Great for people who give a lot of presentations (as we @ moosy do for a living).

So after installing the new office version, we wanted to give this a try. Unfortunately the installation requires quite some work, by default it gave us a library error. Here are the steps for configuring the extension on openSUSE 11.

Step 1 - Prepare OOo libraries
Add this file as root:
/etc/ld.so.conf.d/ooo3.conf
with this line as content:
/usr/lib/ooo3/ure/lib

Afterwards run ldconfig

Step 2 - Install STL library
Still as root, install the stl library from sourceforge:
rpm -ivh ftp://ftp.pbone.net/mirror/ftp.sourceforge.net/pub/sourceforge/w/wi/witme/STLport-4.5.3-9064.i386.rpm

Alternatively, you may install the openoffice devel package, which is 627 MB. Hm, maybe not.

Step 3 - Download extension
Go to extensions.services.openoffice.org to find the right package, or click here to download the 1.0.1 version for 32-bit linux directly.

Optional Step - Check dependencies [expert]
You can choose to open the download with the OpenOffice extension manager or you can save it. When you want to manually check if everything is OK, save it first and follow this step.
In a shell, go to the directory where you downloaded the file.
Run: unzip sun-presenter-screen-linuxintel.oxt, this will result in a lot of files, don't worry.
Now run
ldd PresenterScreen.uno.so
Check the output for "Not found" messages, it should look like this:

linux-gate.so.1 => (0xffffe000)
libuno_cppuhelpergcc3.so.3 => /usr/lib/ooo3/ure/lib/libuno_cppuhelpergcc3.so.3 (0xb7de0000)
libuno_cppu.so.3 => /usr/lib/ooo3/ure/lib/libuno_cppu.so.3 (0xb7db3000)
libuno_sal.so.3 => /usr/lib/ooo3/ure/lib/libuno_sal.so.3 (0xb7d70000)
libdl.so.2 => /lib/libdl.so.2 (0xb7d6c000)
libpthread.so.0 => /lib/libpthread.so.0 (0xb7d53000)
libstlport_gcc.so => /usr/lib/libstlport_gcc.so (0xb7c8d000)
libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0xb7b9d000)
libm.so.6 => /lib/libm.so.6 (0xb7b77000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0xb7b69000)
libc.so.6 => /lib/libc.so.6 (0xb7a26000)
libuno_salhelpergcc3.so.3 => /usr/lib/ooo3/ure/lib/libuno_salhelpergcc3.so.3 (0xb7a20000)
libcrypt.so.1 => /lib/libcrypt.so.1 (0xb79ea000)
/lib/ld-linux.so.2 (0xb7f7b000)

Step 4 - Install extension
If you skipped the optional step of making sure that everything is OK, you are already in the extension manager. Otherwise, start it from the commandline:
/usr/bin/unopkg gui ./sun-presenter-screen-linuxintel.oxt

Follow the simple instructions from the extension manager and you're done.

Now configure a dual-head monitor setup, or attach your projector.
Start OpenOffice, open a presentation and go to the menu Slide Show / Slide Show Settings...
The Multiple Monitors section is activated and you can choose a presentation monitor. Start the presentation (F5) and (click image)...
