Upgrade sage: build from sources?
I'm using an older version of Sage (4.5.3) in Ubuntu 10.04. I like it, but I'd like to upgrade to a more recent version. From the command prompt, calling
$ sage -upgrade
throws a scary warning at me:
** WARNING: This is a source-based upgrade, which could take hours, ** fail, and render your Sage install useless!! This is a binary ** install, so upgrading in place is *not* recommended unless you are ** an expert. Please consider installing a new binary from ** http://sagemath.org instead.
Question: Is there really a significant advantage to building the binaries from source?
I am running a Sony Vaio laptop on 4 2.13 GHz Intel cores. (I can specify more stats if it helps somebody to give me good advice.)
