That seems like a waste of effort -- and 'corrupts' your world file, as
well, since everything you emerge explicitly will be entered into your
world file, and that will then include dependencies, which should by
rights *not* be in your world file, nothing said about dependencies of
dependencies, also known as 'deep dependencies'.

You're really making a mess doing that; you'll screw up emerge
--depclean, for one thing, since I have no idea what it would do if a
dependency of an uninstalled package in your world file (which would
normally make the package a valid target for depclean) is also in your
world file, given that dependencies are not meant to be in your world
file (thereby invalidating the now-useless package as a depclean target):

man emerge

      --depclean
              Determines all packages installed on the system that have
no explicit reason for being there.  emerge generates  a  list  of
              packages  which  it  expects  to be installed by checking
the system package list and the world file.  It then compares that
              list to the list of packages which are actually installed;
the differences are  listed  as  unnecessary  packages  and  then
              unmerged  after  a  short  timeout.  WARNING: Removing
some packages may cause packages which link to the removed package to
              stop working and complain about missing libraries.
Re-emerge the complaining package to fix this issue.  Note that  changes
              in USE flags can drastically affect the output of --depclean.

But if a dependency of an uninstalled package is in your world file
(which in your situation it could be), then it *does* have a reason for
being there (because it's in the world file), so would not be cleaned,
which is just not the way Portage is set up to work.

You might consider changing -p to -a when doing an emerge world
(--pretend to --ask), so that you can see what's being emerged and not
have to go to all the effort of typing the emerge command again (or,
heaven forfend, individual commands the way you do now) You might also
consider adding -u (--update), -D (--deep), -t (--tree) and -v
(--verbose) to  1) catch updated direct dependencies; 2) catch updated
indirect (deep) dependencies, 3) see which packages are requiring that a
dependency or deep dependency be updated; and 4) see what the USE flag
status is for all requested-to-emerge packages.

I don't offhand know how to 'fix' your world file, but I'm pretty sure
that one of ecatmur's utilities, posted on the forums, is likely designed to
solve this issue. I remember a thread called 'Clean out your World
file'... can't find it, but there is this:

Portage utilities not in Portage:

which ought to have something of use.

Hope this helps,
