Bug 219036: ports-mgmt/pkg:  pkg confused, installs older version over newer
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=219036

--- Description ---
(10.3 2017Q2) 

When I did a pan-upgrade, pkg deleted xfce desktop but did not replace it (it
really should *not* delete anything til after it has done the replacement).  So
I had this big gray background and had to figure out what happened and then
re-install by hand.

For some reason not obvious to me, the xfce desktop package includes samba44. 
I already had 46 installed, but pkg 

- didn't check for a later version
- downloaded 44
- THEN discovered 46 and complained
- downloaded ANOTHER copy of 46 
- installed 44 anyway
- THEN tried to re-install 46 and failed, complaining.

That's a lot of confusion, and ended with the wrong version installed.	

Packages should not be made of unrelated parts, for a start. At least 2 of the
4 pieces in the package are unrelated to the desktop.  pkg should preferably
allow parts to be knocked out of the install, rather than make it a yes-no
all-or-nothing choice.	And it should definitely check, *before* downloading,
whether the install would replace a later version with an earlier and avoid
doing that.
