Fetch the package and install it with:
# pkgadd -d distribute.0.6.28.SPARC.64bit.Solaris.10.pkg distribute
Issues To Be Aware Of
This version of distribute has been compiled against the Python 2.7.3 software. You must install that before installing this software.
Some filenames in this software have had spaces and parenthese removed to follow best practices. The relevant scripts were also updated to refer to the new filenames. A bug was logged against the code but a retard newbie thinks it's not a problem.
Each distribute package requires installation on the Solaris release it was built on. Only install the correct version for your system.
