[Biopython] Error with py2exe and Entrez functions

[Nizar Ghneim]

Hello All,

I am writing a short script that others would like to use on their own
computers. I decided to use the py2exe tool to create an executable. The
script runs perfectly in Python, but whenever in my exe file, the first line
to access any Bio.Enterez function (such as esearch or efetch), gives me the
following error:

  File "Bio\Entrez\__init__.pyc", line 258, in read

It seems to me that the py2exe compiler does not grab the necessary DTD
files. How can I solve this?

Thank you in advance,
