reading "Build Files Exist" seems to suggest the package already exists, but it's not, I think.
So what is "CleanBuild" and what do the options mean: [N]one [A]ll [Ab]ort [I]nstalled [No]t Installed
And is meant by (1 2 3, 1-3, ^4) ?
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Cleanbuild means not to use previous existing files, the numbers are exemples of a selection of which packages to cleanbuild. ^4 means all but number 4, the others I think are self explantory
