The "recommended" way?! X) Well, by the cool design, construct the version from the files package-version.txt and probably checksums.ini in build/pkgs/what_you_think_the_basename_in_sage_is/, and compare that to what you may find in $SAGE_LOCAL/var/lib/sage/installed/ [sic]. To go triple-safe, compare the checksum(s) in one of the files mentioned above to that of the upstream tarball (whose name you have to construct as well from the files above) if present. Simple, isn't it? (As a "user", you may simply try './sage -i ...' and see if it says "... already installed".) Note that the "latest" version of any package is always exactly the one hardcoded into the "unified repo" for any given Sage version. -leif -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
