How do I get rid of this routing warning?

map.category ‘product_category/:page/path/:path’,
:controller => ‘product_category’,
:action => ‘show’,
:requirements => {:path => /.+/, :page=>/\d+/},
:page =>1

warning is

“Route segment “:page” cannot be optional because it precedes a
required segment. This segment will be required.”

I don’t understand how :page is optional?

Been googling and reading the code of RouteBuilder but I’ve been
unable to figure it out.
