What steps will reproduce the problem?
1. Install tesseract-ocr, leptonica-1.69 and python-tesseract from source
2. import tesseract from script
3. Also readText method from simplecv fails with " SimpleCV:2: 'Please install 
the correct OCR library required - http://code.google.com/p/tesseract-ocr/ 
http://code.google.com/p/python-tesseract/' 

What is the expected output? What do you see instead?
script should be able to import tesseract

What version of the product are you using? On what operating system?
Fedora18
tesseract-ocr, leptonica-1.69 and python-tesseract from source

I have ..
Downloaded langugage data file (e.g. 'wget
http://tesseract-ocr.googlecode.com/files/tesseract-ocr-3.02.eng.tar.gz'
Decompress it
and set
export TESSDATA_PREFIX=/home/amzn_aiv/Desktop/tesseract-ocr/

Is this what you mean?

I have python tesseract in ubuntu 12.04 LTS working fine.

I want to move to fedora for hardware issues in ubuntu. Can you please help in 
resolving this issue?

Thanks,

I did a fresh install of Fedora and didn't encounter any errors. Are u using 
the svn version of python-tesseract?

Too bad, my compiled version is for Fedora 19
Can you upgrade yours?

Hi .. 

After upgrading to fedora 19, I un-installed and reinstalled rpm, I face the 
same issue..
