add re module to a embeded device phyton interpreter

[odlfox]

   I hav to add the re (regular expressions) functionality to an
Embeded device that I'm using.  I read the re.py file and it says I
need several dependencies, one of them is the pcre module but I found
no pcre.py or pcre.pyc file.  Someone knows where to find something to
solve my problem. Thanks a lot
