bad dependency calculations

[sambler]

Rather than tag onto #1705 I choose to report my experience using pkg separately.

I find pkg regularly wants to remove unrelated packages.

This would be the reason I will never trust the base system install to pkg, having it choose to remove the base system will make the system completely unusable.

I have just upgraded from 14-stable to 15-stable, after install world I ran pkg-static install -f pkg and it wanted to remove 24 packages.

The following 25 package(s) will be affected (of 0 checked):

Installed packages to be REINSTALLED:
	pkg-2.4.2_1 [mts_pkg_home]

Number of packages to be removed: 24
Number of packages to be reinstalled: 1

I kill that and run pkg upgrade and get

Number of packages to be removed: 40
Number of packages to be installed: 190
Number of packages to be upgraded: 1821
Number of packages to be reinstalled: 1484

then kill that and run pkg install xorg and get

Number of packages to be removed: 338
Number of packages to be installed: 23
Number of packages to be upgraded: 103
Number of packages to be reinstalled: 48

I ended up force installing everything using cat /root/tmplist | xargs pkg install -f with tmplist being a file of port origins that were previously installed and successfully packaged in my poudriere.
