Note: This version of the VDT (1.5.1) is no longer supported. Feel free to look through the documentation and install it, but we cannot guarantee support for it. The current stable release is 2.0.0.

Python

When is Python installed by the VDT?

Whenever possible, the VDT tries to use the Python binaries already installed on your system. However, sometimes that is not possible or highly inefficient. In those cases the VDT installs and uses a copy of Python instead.

PyGlobus/PyGridWare

PyGlobus requires a complete install of Python >= 2.3. If your Python install is incomplete (usually missing the python-dev package) or too old the VDT Python will be installed and added to the path.

Clarens

The Clarens web services framework is deployed using the mod_python Apache module. This module requires that the same version of Python that it was built with is available at runtime. Thus, when installing Clarens, the VDT also installs the correct version of Python needed by the VDT's mod_python package. Please note that the binaries from the VDT's Python installation are not added to your environment's PATH variable and you will continue to use your system's Python version.
