[gentoo-user] Ruby is infesting my machine

[Andrew Lowe]

Hi all,
    Just done an "eix-sync" followed by an "emerge --pretend -NuD world"
and for some reason, something wants to install Ruby stuff everywhere -
I don't currently have any ruby stuff installed. I have in my make.conf
"-ruby" and "RUBY_TARGETS=""". Looking at "equery depends ruby" shows 4
ebuilds,

app-text/docbook-xsl-stylesheets-1.78.0-r1 (ruby ? dev-lang/ruby:1.9)
                                           (ruby ? dev-lang/ruby:2.0)
dev-util/universalindentgui-1.2.0-r1 (ruby ? dev-lang/ruby)
dev-vcs/subversion-1.8.13-r2 (ruby ? >=dev-lang/ruby-2.1:2.1)
media-gfx/graphviz-2.38.0 (ruby ? dev-lang/ruby)

I've gone into package.use and put a "-ruby" for these four and the
problem persists.

Looking at the output from "emerge --pretend -NuD world" shows the first
mention of ruby is "eselect-ruby". Putting this into package.mask does
nothing, it still appears in the emerge list and now also at the bottom
of the emerge output under "The following mask changes are necessary to
proceed"

"emerge --tree --pretend dev-lang/ruby" appears to also have
eselect-ruby as the cause of the trouble.

	Does anyone know how I can prevent this infestation from happening?

	Regards,
		Andrew

It may not be possible since some packages require ruby to be present 
unconditionally, e.g. webkit-gtk has a built-time dependency on ruby, and 
the thin-provisioning-tools have a dependency on ruby with FEATURES=test. 
There are other packages with similar requirements.

	Valid point, but shouldn't putting "-ruby" in make.conf throw up all
sorts of warnings/errors?

No, because USE flags control *optional* dependencies and features. If a
package requires Ruby, it will not have the ruby USE flag because you
cannot turn off a hard dependency.

If you really need to see what wants Ruby, add --tree to your emerge
world command.

# equery depends ruby

Might shed some light too.

	To close off my original question, the problem was related to
qt-creator. I had 3.2.2 installed and it wanted to update to 3.4.1.
3.4.1 has a dependency on qtwebkit, which has a dependency on ruby,
hence the infestation. Masking > 3.2.2 solved the problem.

	Thanks to those who provided suggestions,

		Andrew

p.s. "--tree" really needs to be documented properly somewhere

--tree is already documented in the man page, in alphabetical order with
all the rest of the options. Yes, it's two lines, but that's all it
needs to be:

it displays the whole depgraph so yu can see what pulls in what.

It's also *very* well-known around here and is usually one of the first
things given as advice with questions like yours.

Were you expecting something more?
