In a real database, you would be able to do something like

select distinct OS,
                RELEASE,
                (select count(1) from $table as y
                                 where x.OS=y.OS and x.RELEASE=y.RELEA
+SE and y.LIKE='Yes'),
                (select count(1) from $table as y
                                 where x.OS=y.OS and x.RELEASE=y.RELEA
+SE and y.LIKE='No')
       from $table as x;

For some reason, it works in SQLite, but CSV returns

DBD::CSV::db prepare failed: Unbalanced parentheses! at .../perl/lib/p
