Of course it's true that people don't just compile things by luck, but 
it's also true that the issue is kind of beyond cpython. The best you 
could really expect is for cpython to say the following libraries with 
the following major numbers are required (possibly with links to the 
websites for the sources). It's out of the cpython programmers control 
how these libraries are made available on the many different systems and 
distributions that python is used on. If you use it on distro a and you 
want to compile it, it's basically your responsibility to figure out how 
to get the libraries.

So really the main conclusion is that you should probably figure out how 
to use your distribution wisely to find this information. For any 
systems providing something similar to apt-get build-dep it's pretty 
easy (which _is_ your situation and hence you have already solved your 
problem). For others...well if you choose to use such a system it's your 
responsibility.

As much as it was irritating not learning these tricks earlier, you do 
now know them and should be fine going forward...

Cheers,
Thomas
