Finally I got building tesseract, but honestly i don't know how ... I
submitted many times the same code you posted, but only few days ago it
worked.
Here is the working *Prebuild.sh*:

Attached to this post you find the full building log.
You can see few warning/errors that seem not to stop the building process,
but that end up to affect tesseract execution because if I run this basic
python code:
*wsgi.py*:
> import subprocess
> def application(environ, start_response):
> status = '200 OK'
> response_headers = [('Content-type', 'text/plain')]
> start_response(status, response_headers)
>
> args = ['/home/dotcloud/local/bin/tesseract',
> 'eurotext.tif','eurotext.txt']
> p = subprocess.Popen(args, stdout = subprocess.PIPE, stdin =
> subprocess.PIPE, stderr = subprocess.STDOUT)
> preprocessed, _ = p.communicate()
>
> return [preprocessed]+[_]
I got this:
Error in findTiffCompression: function not present
> Error in pixReadStreamTiff: function not present
> Error in pixReadStream: tiff: no pix returned

I'm sure what I miss are those libs (
http://code.google.com/p/tesseract-ocr/wiki/ReadMe):
sudo apt-get install autoconf automake libtool
sudo apt-get install libpng12-dev
sudo apt-get install libjpeg62-dev
sudo apt-get install libtiff4-dev
sudo apt-get install zlib1g-dev
but, again, I don't how to install them without sudo.
Thank you all
