BuddyPress install to sub-site on subfolder network

I have a network install working right. I installed the BuddyPress plugin.

It's a new site with the main site at .../ and an additional one at .../social/.

I would like BuddyPress installed on the .../social/ site; not on the main one. This is to keep the menu structure for social interaction separate from other portions of the site.

I have not gone through all five BP set up steps yet. It looks like BP setup attempts to set all of the pages up in the main site, even though I started the setup from within the .../social/ site.

Is there a way to make sure that the BP pages only reside in the /social/ site folder?; not under the full main site?
