It would have been helpful to have put the error lines in the email
and a link to the full log.

Based on google results and other people having the same issue, you may not
have swig installed. It is something to install with npm from what I
see. Other people
have it but need to set some variables to let cmake know where it is.

Hopefully installing it will help. Chris should comment on this from
an RSB perspective.
