 Hello,

 Copying the port php_select to create php5_select and php7_select,
 everything goes well but the uninstall process.

 The select table keeps the entries. The same behaviour occurs with the
 original php_select basis I followed.

 What should be added to the Portfile (or other) to clean the select table
 during the uninstall process ?
