1. Delete C:\Python27\ArcGIS10.2\site-packages\DTBGGP64.pth. pth files should only point to modules that are of the same type x32 or x64. Your spss modules are x64 so you cannot import them in ArcMap foreground processing - which is always 32 bit python.
2. To avoid breaking python paths needed for ArcGIS, you can take advantage of the fact that .pth files are loaded in alphabetical order. To force the spss stuff to load last so it won't break ArcGIS, you can try renaming your file DTBGGP64.pth to zzDTBGGP64.pth -- again, in the Python x64 site-packages folder ONLY.
3. This may or may not work depending on the dependencies in the spss modules -- which may be different from ArcGIS. There are situations where you need to install a separate Python and run it using the subprocess module in its own thread.
Note that to get any of these changes to take, you need to restart Python. In the case of Desktop, that means you need to shut down ArcMap/ArcCatalog and start it again to restart the in-process Python session.
Hope this helps you out!
