A business template exported by Python 2.4 may contain:

<klass>
  <global id="xxx" name="_compile" module="sre"/>
</klass>

A business template exported by Python 2.6 may contain:
<klass>
  <global id="xxx" name="_compile" module="re"/>
</klass>

Python 2.6 provides 'sre._compile', but Python 2.4 does not provide
're._compile', so we provide re._compile here for the backward
compatilibility.
