Comment 9 for bug 979524

Adding a note to this - in my /tmp dir, a sikuli directory already exists, thus I could not create the link there.
First I did a:
sudo rm -r /tmp/sikuli
followed by Florian's suggestions above (prefaced with sudo):
sudo mkdir -p /tmp/sikuli
sudu ln -s /usr/share/tesseract-ocr/tessdata/ /tmp/sikuli

After this, I do not have the crash associated with libtesseract.so.3

Very happy that sikuli is working now on my Ubuntu 12.04.
In summary, after doing the:
sudo apt-get install sikuli-ide
to get sikuli installed, you must also do (again, Florian points this out earlier):
sudo apt-get install tesseract-ocr-eng
sudo apt-get install libswing-layout-java
and wrap up with what I stated at the beginning of this:
if there is a /tmp/sikuli directory, do: sudo rm -r /tmp/sikuli
and wrap up with:
sudo mkdir -p /tmp/sikuli
sudu ln -s /usr/share/tesseract-ocr/tessdata/ /tmp/sikuli

That's how I got sikuli to run as expected on Ubuntu 12.04.
