[gentoo-user] Provide a package for a special PHP version / slot / USE flag?

[Matthias Hanft]

Hi,

since dev-php/pecl-haru seems not to be available for PHP 7,
I installed it myself from github.  But at every emerge, it
tells me about unmet dependencies.  Of course, I could remove
the pecl-haru package completely from @world and just use my
self-installed "version 7".  But for a short time, I need both
versions in parallel (i.e. the 5.6 version from portage tree,
and my own 7.3 version from github).  I know (and already used)
the "packacke.provided" mechanism, but it seems that I cannot
"provide" certain slots, PHP versions, or USE flags there.

Is there a way to prevent portage warnings and errors in this
case?

Thanks,

-Matt
