Hm, i totally don't agree with the original comment from the bug. Many people
get use of those two flags without even noticing it. There is bunch of good
soft, that take advantages of perl modules or python bindings/wrappers. For
servers it may be nagios-plugins with bunch of perl scripts for hosts
monitoring or at least nice DBD::mysql.

So, maybe it's better to disable such flags on your system if you don't like
them - that's why you are using Gentoo, aren't you?

David,

in the cases you mention, there's also the option to enable those use
flags through IUSE defaults or if we're talking exclusively about server
packages, thorough the server profiles.
As explained in the bug, at least the python use flag means very heavy
and *problematic* deps for KDE. As the current USE_ORDER prevents "-use"
flags from working on ebuilds, any flag set by the profile requires
users to "manually" disable it in /etc/portage/package.use[/*].

I think this is probably a good idea after EAPI 2 is stable and we
eliminate built_with_use usage from the tree. I think having stuff build
out of the box instead of dying in the middle of emerge outweighs
pulling in some extra stuff with default settings.

If one has built a system with the default python and perl USE flags,
what steps would be necessary to remove all packages and dependencies
after removing them from the USE declarations?

After kicking 'em out of make.conf, run emerge -pvtuDN world (the N is
important; it tells emerge to look for USE flag changes). Once you've
rebuilt your packages, then you can run emerge -p --depclean.

Re: Proposal: disable python and perl USE flags in profile [In reply to]

Hmmmm, that's what I assumed, but I run into problems with the depclean:

Dependencies could not be completely resolved due to
the following required packages not being installed:

>=virtual/perl-Compress-Zlib-1.14 required by dev-perl/Archive-Zip-1.23
>=virtual/perl-ExtUtils-ParseXS-1.02 required by
perl-core/Module-Build-0.28.08
>=virtual/perl-ExtUtils-CBuilder-0.15 required by
perl-core/Module-Build-0.28.08
>=virtual/perl-Archive-Tar-1.09 required by perl-core/Module-Build-0.28.08

Have you forgotten to run `emerge --update --newuse --deep world` prior to
depclean? It may be necessary to manually uninstall packages that no longer
exist in the portage tree since it may not be possible to satisfy their
dependencies. Also, be aware of the --with-bdeps option that is documented
in `man emerge`.

Thanks for the information Josh.
