Note: This version of the VDT (1.3.9) 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 inneficient. 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 uses the mod_python Apache module. To save time during the install we build mod_python beforehand. This requires that the same Python version be available at runtime. If you install Clarens the VDT Python will be installed by not added to the path.
