https://ask.sagemath.org/question/25880/sage-install-error/?comment=25882#post-id-25882Can you tell us a bit more? Please edit your question:
(a) Do you have Mac OS X 10.x.y? Ubuntu x.y? Other?
(b) Did you download source or binary? From what page?
(c) What commands did you run?

https://ask.sagemath.org/question/25880/sage-install-error/?answer=25901#post-id-25901I suppose the OS on your computer is GNU/Linux.
Try installing `libm`, maybe by running the following command in a terminal.
sudo apt-get install libm
and try building Sage again.Mon, 23 Feb 2015 14:29:18 -0600https://ask.sagemath.org/question/25880/sage-install-error/?answer=25901#post-id-25901
