Fedora 7 has reached "end of life" (see
this) and is therefore no longer supported. You should upgrade to a newer, supported version of Fedora (12 appears to be the latest). As for installing Ambulant Player, first check if Fedora provides a package for it. If not, then it seems you'll have to get the source code from
www.ambulant.org and read the instructions that can also be found on the same site (
http://www.ambulantplayer.org/Download200s.shtml).
