Hans,

Thank you, I understand.

Apparently I have to add some ruby_targets_ruby19 USE flags to my
system.  I pasted a snippet of my /etc/portage/package.use below.  I
included some other entries for context.

Question 1: Is it true that, except for this new RUBY stuff, every
entry in my package.use file is an attempt by me to enable some
feature I want in a package I want?

Answer 1: Yes

Question 2: Does it seem weird that portage wants me to add USE flags
to enable some feature in a package I never heard of and have no
interest in and to top it off has a very weird name
(ruby_targets_ruby19)?

Answer 2: [your answer here]

The tone of this message might sound obnoxious, but it's just a
"trick" I am using to better ask my question.  I'm not complaining (I
don't even know enough about this to have a complaint), I'm really
just curious.

Thank you,

Chris
