Reading between the lines, I guess that John has set up his Centos boxes without development tools. I've known sys admins like that: in an effort to "increase security" they take away dev tools so that anybody breaking in can't install anything underhanded, at least in theory. With all the tools installed, it's a matter of a few minutes effort to build from scratch: download the tar ball extract the contents of the file cd into the source directory run ./configure run make optionally run make test run sudo make altinstall As a total n00b who'd never used make before, it took me 25 minutes effort on my first attempt, including reading the entire README file (twice!). Now I have the whole process down to about 30 seconds effort, and six minutes elapsed time, on my laptop. But obviously you can't build from source without a compiler. So under those circumstances, it would be very difficult to build from source, as you need to install make, gcc, and who knows what other tools, and fight with the cryptic error messages generated until eventually it all Just Works. I hate to imagine how much effort would be involved. And I can't fathom why John imagines that this is Python's fault. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
