Not sure what the problem was, but it was still giving me an error message after installing 12.04 and doing sudo apt-get install tesseract-ocr (and following the steps in previous posts). This time, the error was that it couldn't find the file liblept.so. Anyways, I did the installation steps with leptonlib-1.67 and then doing ./configure with tesseract-ocr-read-only (3.02) worked. However, when I do make, it gives the following error message:

I'd really like to get this working. Somehow, I think if I can remove all tesseract/leptonica files from my computer and start again from scratch, it would work fine.
