Unknown column 'share_name' with Owncloud on Gentoo

Hi, All:

I’m running Owncloud (on Gentoo), and was alerted that Sharing (creating a link share) doesn’t work.
Sure enough, using the web-interface AND the Android Client, I get:

An exception occurred while executing 'INSERT INTOoc_share(share_type,token,parent,share_name,item_type,item_source,file_source,permissions,uid_initiator,uid_owner,file_target,stime) VALUES(?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)' with params [3, "HgroxNK0WeaCXvE", null, "Bear Creek Camping 2018 link", "file", 1497546, 1497546, 1, "gordp", "gordp", "\/Shared\/Bear Creek Camping 2018", 1544722026]: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'share_name' in 'field list'

I’m using MySQL as the database; can someone suggest exactly how I can remedy this issue (ie provide a sequence of suitable mysql commands)? Thanks in advance!
