This is not an April fools joke.

In some cases it sucks. I could go on and on, but won't, since this issue has
already been addressed above.

No, of course not -- Python comes with the Sage binary !?

Is there even *one* operating system that building Sage from source
officially supports that doesn't
include Python by default or with their build-essentials package
(which is needed to build sage)? I've asked this multiple times in
this thread now, and nobody has replied.
Here is the list of supported platforms, from the README.txt:
PROCESSOR OPERATING SYSTEM
x86 32-bit Linux -- Debian, Ubuntu, CentOS (=Red Hat),
Fedora, openSUSE, Mandriva
x86_64 64-bit Linux -- Debian, Ubuntu, CentOS (=Red Hat),
Fedora, openSUSE, Mandriva
IA-64 Itanium 2 64-bit Linux -- Red Hat, SUSE
x86 Apple Mac OS X 10.5.x
PPC Apple Mac OS X 10.5.x
Use Sage on Microsoft Windows via VirtualBox. We do not always test on
OS X 10.4, but Sage should work there fine.
---
In each case above, the Linux distro is meant to be the latest stable
released version.
