[gentoo-dev] Abusing PROVIDE

[Tom Payne <twp@gentoo.org>]

Hi --

I'd like to abuse PROVIDE. Here's the story:

ruby-1.6.8 is the latest version of Ruby
rexml, yaml, optparse, and others are available as add-on packages

ruby-1.8.0 is coming Real Soon Now
rexml, yaml, optparse, and others are part of the ruby-1.8.0 distribution

If a package needs ruby and optparse I can write
DEPEND="( >=dev-lang/ruby-1.6 <dev-lang/ruby-1.8 dev-ruby/optparse )
	|| >=dev-lang/ruby-1.8.0"
but this means that I have to modify every ebuild that depends on any of
packages that are now part of ruby-1.8.

Question: is it OK to make dev-lang/ruby-1.8 PROVIDE rexml, yaml, etc.? e.g.
PROVIDE="dev-ruby/rexml dev-ruby/yaml dev-ruby/optparse"
Or will this cause problems?

Cheers,

Tom
