Thanks, that was the issue. Everything runs normally now.

You need to install the boost libraries, see this sage-support thread.

We're following up on this bug (boost is not a required runtime dependency) at this sage-devel post and Trac 12963.

Hello everybody,

(Sorry for the long code quoting.)

I'm trying to run Sage 5.0 (the binary version) on fedora 16. After launching Sage from terminal I get the following message:

==================================================================
