why not create links? It saves disk space and CPU cycles.
Well, we copy the library, and the user might decide to upgrade the system
libreadline (devel version) later, perhaps even "unintentionally" by
installing a bunch of upgraded packages.
We then might use newer headers that do not match the library we copied,
which would break a later [re]build. So it's safer to copy them, too. My
readline 6.1 headers are 80 KB btw.
(For the same reason I prefer '''copying''' the library, since otherwise
an upgrade of the system library might break '''our''', the Sage
installation.)
