Out of the box installation gives poor results #671

What steps will reproduce the problem?
1. Compile / Install 3.01 
2. Run on a known image file

What is the expected output? What do you see instead?

Looking at the output shown in issue 596 
(http://code.google.com/p/tesseract-ocr/issues/detail?id=596), I would expect 
quality similar to that.  I ran my version of tesseract on that same file 
(3.png) and get poor results comparatively speaking.

As you can see there is a big difference in quality!

What version of the product are you using? On what operating system?

I have tried with both 3.00 and 3.01 (3.01 is a bit better).  OS is CentOS 5.4. 
 I have built Leptonica 1.68.  Attached is some additional version info 
(tesseract-3.01-ldd.txt).

Please provide any additional information below.

I have also added my comments to issue 596 as it seemed potentially relevant at 
the time.
My belief is that I have made some kind of 'schoolboy' error - can someone 
please guide me on what it is?
Thanks.
