This is a "feature" of the OS X installer I haven't figured out how to
disable. Instead of installing in /Applications where you want it, it
searches the hard drive for anything that looks like a previous
installation and puts it there instead. You can tell it's happening by
opening Console, then install.log, and looking for lines like this:

Jan 15 13:42:55 mac-mini pkgExtractor[50173]:    Diverting "./Zenmap.app" to 
"/Users/david/nmap/macosz/zenmap-build/zenmap/dist/Zemap.app"

The created and modified times on the directory might not get updated
when a new version is installed.
