The purpose of -a (ask) is so you can see the stuff before taking action, and if it needs rebuilding then do it. Nothing is rebuilt just because it shows up in the output; but not seeing changes to a package you use that were made is not too bright. If you ever built from source before, I'm sure you didn't blindly build the software without reading ./configure --help and checking your options. -- Happy Penguin Computers >') 126 Fenco Drive ( \ Tupelo, MS 38801 ^^ [email protected] 662-269-2706 662-205-6424 http://happypenguincomputers.com/ Don't top-post: http://en.wikipedia.org/wiki/Top_post#Top-posting
