[osgeo4w-dev] ImportError: OSGeo4W problems with Python/GDAL

Hi folks,

For what it's worth, what enabled me to find the conflict with 
libeay32.dll on my machine, was the method outlined earlier:

  * opening a fresh command shell,
  * completely stripping all PATH and PYTHON* environment variables,
  * slowly adding the paths back in one at a time until the problem
  * examining the contents of latest folder added,
  * remove .dll's from that folder until it works again

I'm not that familiar with Dependency Walker but when looking at 
"Options > Module Search Order" I see it does make use of the PATH of 
whichever shell started it -- meaning you need to start depends.exe from 
within the Osgeo4w shell or it will use the default Windows user profile 
environment instead.

Error references to IESHIMS.DLL in the Dependency Walker thus seems like being a wild chase.
