I have tried to install Sage 7.1 on my Ubuntu 15.10, it does not work. Here
is the tail of the log when I enter "make":

Error building Sage.
The following package(s) may have failed to build (not necessarily
during this run of 'make all'):
* package: sage-7.1
log file: /home/mydocuments/SageMath/SageMath/logs/pkgs/sage-7.1.log
build directory:
/home/mydocuments/SageMath/SageMath/local/var/tmp/sage/build/sage-7.1
The build directory may contain configuration files and other potentially
helpful information. WARNING: if you now run 'make' again, the build
directory will, by default, be deleted. Set the environment variable
SAGE_KEEP_BUILT_SPKGS to 'yes' to prevent this.
Makefile:16: recipe for target 'all' failed
