I already Unzipped the plugins directory and put it on /usr/share/ocsinventory-reports/ocsreports/extensions, but I needed to changed the first letter of the library to uppercase, and rewrite script (install_plugin.py) map.pm to Map.pm, on /usr/share/ocsinventory-reports/ocsreports/tools. After all these proccess, I could to install all plugins.
Since I installed the plugins on my OCSInventory server 2.6RC, no data comes to database! Even when I put the *.vbs on C:\Program Files (x86)\OCS Inventory Agent\Plugins and force to Run OCS Inventory Agent.
I think that the install.php, inside plugin directory, don't "install" the application! Somebody could help?!!!
