Whether numpy is installed in the system or not does not matter for the
Sage installation. Sage uses its own virtual environment without access to
system Python packages.
Please switch to the latest development branch using "git checkout" and use
"make distclean" so that the source tree is clean
Check that /usr/local/ does not contain libraries that shadow system
libraries. In particular, check /usr/local/lib/pkgconfig
Then a new build using "make build" should work; if there is a new failure,
please send the logs, including config.log
