Comment(by glynn):

 Replying to [comment:26 hamish]:
 > As seen in the pdf screenshot, the trouble comes with "import re", which
 I think(??) is a built-in.

 re.py and sre_*.py are part of the standard library. The error comes
 because MAXREPEAT is expected to be in the binary module "_sre", which is
 built into python27.dll. This is getting loaded from the Windows/System or
 SysWOW64 directory, hence the problem.

 > Are we prepending to the PYTHONPATH instead of adding the grass paths to
 the end of it? (hopefully the GRASS versions get picked up first then)
 AFAIK env.bat & friends in the stand-alone installer now explicitly set
 GRASS_PYTHON with with the full path to grass's python.exe.

 I don't know whether imports from the standard library use PYTHONPATH or
 PYTHONHOME (and neither of those will affect binary modules built into
 python27.dll).
