Search the DistroWatch database for distributions using a particular package. If you are looking for a distribution with the latest kernel, select "linux" from the drop-down box below and type the version number into the text box next to it. Please note that the best way to obtain the GNOME version is by searching for "nautilus", while KDE is represented by the "kdelibs" package. Apache 2.x is listed as "httpd". As for versioning, try to be as close to official version numbers as possible: as an example, for libgnome you should type 2.8.0 (not 2.8) and for kdelibs 4.7.4 (not 4.7). Have fun and let us know how we can improve the search engine!
