Hi Jason,
the Sage README.txt says:
"
QUICK INSTRUCTIONS TO BUILD FROM SOURCE
---------------------------------------
The following steps briefly outline the process of building Sage from
source. More detailed instructions, including how to build faster on
multicore machines are contained later in this README and in the
Installation Guide:
http://www.sagemath.org/doc/installation
1. Make sure you have the dependencies and 3 GB of free disk space.
Linux: gcc, make, m4, perl, ranlib, and tar.
(install these using your package manager)
On recent Debian or Ubuntu systems (in particular Ubuntu 12.04
"Precise"), you need the dpkg-dev package.
OS X: Xcode. Make sure you have installed the most recent version
of Xcode. For pre-Lion versions of OS X, you can download Xcode
from http://developer.apple.com/downloads/. For OS X Lion, you can
install it using the App Store. With Xcode 4.3 or later, you need
to install the "Command Line Tools": from the File menu, choose
"Preferences", then the "Downloads" tab, and then "Install" the
Command Line Tools.
"
As mentioned in this thread, one can install those (e.g. "late march")
command line tools independently of XCode, but they are indispensable. They
install (amongst other stuff) what in Linux land would be called "kernel
headers" and "C library/runtime headers", in OS X nomenclature this is
named "SDK". Sage does bundle GCC now, but not some C library/runtime ---
nor, what is more important, any respective system headers. In Debian
Linux, the couterpart of these "command line tools" would be the
"build-essential" (AFAIR) metabundle, so the requirement to have this
available when trying to build C sources, is not really OS X specific. (But
with XCode 4.2 and earlier, this came more or less automatically as a part
of XCode, which is no longer the case with the "fully application-like"
XCode 4.3 and younger).
Hope that helps!
Cheers,
Georg
