 The xerces-c-vc9-3.1.1-3-devel.tar.bz2 tar file in the
 x86\release\xerces-c folder seems to be compressed in a way that stops
 python from decompressing it. All other files on the site are fine but
 this one returns the following error:


 {{{
 import bz2
 import tarfile

 file ='xerces-c-vc9-3.1.1-3-devel.tar.bz2'
 bzf = bz2.BZ2File(file)
 try:
    tarf = tarfile.TarFile(fileobj=bzf)
    tarf.extractall(working)
 finally:
    bzf.close()
 }}}

   File "build_nsis.py", line 94, in <module>
     tarf = tarfile.TarFile(fileobj=bzf)
   File "C:\OsGeo4W-LINZ\apps\Python27\lib\tarfile.py", line 1574, in
 __init__
     self.firstmember = self.next()
   File "C:\OsGeo4W-LINZ\apps\Python27\lib\tarfile.py", line 2319, in next
     tarinfo = self.tarinfo.fromtarfile(self)
   File "C:\OsGeo4W-LINZ\apps\Python27\lib\tarfile.py", line 1239, in
 fromtarfile

     buf = tarfile.fileobj.read(BLOCKSIZE)
 IOError: invalid data stream

 I've double checked my downloaded file and it ok. tools like tar and 7z
 can actually decompress the tar.
