Manpages are completely separate from executables. They reside in /usr/share/man (and perhaps /usr/local/share/man—not sure if that's used). Manpages for user commands are in the 1 category, so they'd be in /usr/share/man/man1. If there is a manpage, it's possible that another manpage exists with the same name, but in a different category (such as a system call). In that case, running "man 1 http" will restrict man to only look for a user command manpage.
