It seems mongodb has been removed from the official archlinux repository and it seems compiling is out of the question since I need it on a raspberry pi (source). I can't seem to find any helpful page on the internet about this and my experience with archlinux is basically non-existent, so I'm at a bit of a loss here. Where could I find a safe binary of mongodb for archlinux?

(Interestingly, mongodb-tools is still available, although this doesn't make much sense without the db itself ...).
