I have tired to install it with apt from the extras rep.
It installs fine, but I'm having trouble running it.
So I was hoping someone could help me out.

I get the following error when I run tesseract command:
Error: Unable to open /home/opt/maemo/usr/share/tesseract-ocr/tessdata/eng.inttemp

I have searched, there are 2 instances of the file:
1. in /home/opt/maemo/usr/share/tesseract-ocr/tessdata/eng.inttemp, which is a symbolic link that point to itself.
Actually it points to /opt/maemo/usr/...
But since there is a symbolic link between /opt -> /home/opt, it points to itself.

2. the second one is in /media/n900/proc/self/root/proc/4705/cwd/tessdata (2)/eng.inttemp, but I doubt that this is the right one.

I can just copy the file from source over the link, but that is dirty.
