Backtrace parsing exports of a DLL

When using pefile through peframe I get the following backtrace:

$ peframe.py --export tmp/module.1136.9c90da0.2df0000.dll 
Traceback (most recent call last):
  File "/usr/local/bin/peframe.py", line 380, in <module>
    show_exported_functions(filename); sys.exit(0)
  File "/usr/local/bin/peframe.py", line 193, in show_exported_functions
    exported = pecore.get_exported_functions(filename)
  File "/usr/local/bin/modules/pecore.py", line 405, in get_exported_functions
    for exp in pe.DIRECTORY_ENTRY_EXPORT.symbols:
AttributeError: PE instance has no attribute 'DIRECTORY_ENTRY_EXPORT'

---

For reference, LordPE can parse the export table of this DLL. I can provide the 
DLL if needed.
