Just checking, they sounded very similar.

That may not have been enough, those lists date from a time when it
wasn't known exactly which packages to install and were a 'best guess'.
There is however, a big heading on that page:
Packages Required to build Samba
Underneath that it says:
Verified Package Dependencies
There are then the download links to the packages required to build
various Samba versions on different OS's
I suggest you download the bootstrap.sh for Centos 8 under the Samba
4.15 heading
Do not bother with the 'Samba master' one, it doesn't seem to exist
(HINT, HINT to whomever maintains the links)
There appears to be a lot more packages there, though some (if not all)
may have been pulled in as dependencies of other packages that were
already installed or you installed.
If there are extra packages required, you may have to recompile.
