Uploading the file now.
Once you unzip it be sure and edit your python path correctly in the pygimp.interp file.
For instance mine reads -
You will want to adjust the path F:\ - ie ... anything before Gimp_Portable-2.6.11 should be edited to the path you installed it to.
There are a few deprecation errors (pycairo, object, and gtk), when firing up the Python Console but they don't do any harm or hinder running the python scripts.The console still works.
Download is hereGimp-2.6.11 Portable with python
