Hi, First time poster. I have run into the same problem as the OP, so I wonder if there is an update to this I pretty much came up against all the same problems, although I configured apache slightly differently to use the sage version python - I set it up so that Django is run in daemon mode, as I have another Django site running on the same server.
However I have run into the same block at the end libcsage.so: cannot open shared object file: No such file or directory However if I run serve exactly the same Django site using the Django development server instead of apache, then no problems. I can't use the dev server for a production site so I am stuck Any thoughts or updates on this?
