If we search `gpart` utility at `https://www.freebsd.org/cgi/man.cgi` without specify Manual section (`All Sections`) with search target `FreeBSD *-RELEASE and Ports`, we found `gmap` program manual page. But mostly users need `gpart(8)` as more frequently using program. Besides, gpart(8) will shadow gpart(1) as it installs in "/usr/local/bin" directory wich is further in $PATH enviroment variable. Won't it be better to rename `gpart` program in this pakage?
Are you thinking this is referring to biology/gmap? 'Cuz it doesn't install any man pages. cad/scotch has gmap and gpart, though.
Just tried this again and gpart(8) came up first when using the default "All sections". Closing this PR as it no longer seems to be an issue.
