The psmisc package only conflicts with pstree<=2.16 (current pstree
version is 2.19), and pstree itself doesn't conflict with anything.

They are not the same.  In fact, sysutils/psmisc requires procfs to be
mounted, whereas sysutils/pstree does not.  That's why I prefer the
latter.  I'll just rename it to pstree manually. :-)
