This site doesn't always have the answer but it can be a good place to
start.  It works for the most common stuff at least.  However, if no one
shares data with the site that has some obscure package or command, it
reports no hits.

I did a couple searches but it might be that you had typos in at least
one of the file names you are looking for.  You may want to try the
search and make sure you have the names spelled correctly. 

Another thing to consider, you could have a USE flag disabled that needs
to be enabled to turn on the features you want.  That may be needed for
more than one package. 

Hope this helps.
