The problem occurs at the line

  module = __import__(moduleName, globals(), {}, [name])

in importNameFromPlugin in wikiutil.py.

In a new wiki, where it works, importNameFromPlugin is called thrice
with moduleName equal to <wiki>.plugin.macro.XYZ and name equal to
'Dependencies', followed by three calls with name equal to 'execute'.

For the converted wiki, importNameFromPlugin fails on the very first of
the equivalent calls (with name equal to 'Dependencies') with
'ImportError: No module named plugin.macro.XYZ'.

MoinMoin is definitely reaching the macro directory, because if I remove
__init__.pyc it gets recompiled. Also, the correct list of macros is
assigned to 'modules' within __init__.py. 

I'm baffled as to why this isn't working.
