Hello,

You can see the result here:
https://docs.google.com/spreadsheet/gform?key=0AnHn-aw3eaotdE1jM1JSTGdHVV8wTWZxenV4cEkwVlE&gridId=0#chart

The outcome for package manager is pretty obvious, oasis-db should focus on OPAM as a package manager. This is now on my todo list,

Concerning build system:
- ocamlbuild is first (60%)
- native Makefile is second (40%)

So I'll probably focus on this two build systems, which represents at least 70% of what people need (the 3rd build system is less than 30%).

Cheers
Sylvain Le Gall
