[BioPython] Martel Parser error...

[Michael Mayhew]

Greetings,

  I am using BioPython-1.42 (also tried 1.43) on Mac OS X (10.4.8) and 
have successfully compiled/installed the prerequisite packages (Numeric 
and mxTextTools).

  I have been receiving a Martel Parser error as detailed in the 
following readout (from a python interactive session), when I try to use 
either Fasta.RecordParser() or Fasta.SequenceParser() instances:

      >>tester = iter.next()
       Traceback (most recent call last):
     File "<stdin>", line 1, in <module>
     File 
"/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/Bio/Fasta/__init__.py", 
line 72, in next
       result = self._iterator.next()
     File 
"/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/Martel/IterParser.py", 
line 152, in iterateFile
       self.header_parser.parseString(rec)
     File 
"/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/Martel/Parser.py", 
line 356, in parseString
       self._err_handler.fatalError(result)
     File 
"/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/xml/sax/handler.py", 
line 38, in fatalError
       raise exception
   Martel.Parser.ParserPositionException: error parsing at or beyond 
character 0

  I confirmed this when I ran the included test suites (with python 
setup.py test).

  I have seen some suggestions to get the most recent CVS version of 
biopython to rectify this problem. How would I go about this?

  Is getting the most recent CVS version of biopython the only/best 
thing to do?

  Thanks in advance.
