Looks like a broken bash/sh script of some sort. "PS1" is the environment
variable containing the shell prompt. The fact that the shell complains that
"PS1: command not found" means that a script is trying to execute "PS1 ...".
I would look for that string without a leading "$" (which would be needed for
the shell to properly interpret it).
Since this shows up right after the "last login" line, it appears this is in
your startup sequence somewhere (see Volker's response).
Was this the sage binary or the sage ".app"?
