To install SyncEvolution you need to be root (devel-su / rootme).

dpkg -i filename.deb

should install SyncEvolution.

Configuration can be set up at /home/user/.config/syncevolution/

And please read as much as possible at http://wiki.maemo.org/Sync/Usage_of_syncevolution and at https://syncevolution.org/documentation/getting-started.

There will be no SyncEvolution account visible at your N9, but you can manage everything from the command line.
