Welcome to the giant clusterfuck that is RubyWorld(tm). Just be thankful |
| 25 |
you don't have to support corporate internal code written in it. Or |
| 26 |
package gems. |

| 28 |
OK, so disclaimer up front. I detest Ruby. I hate it with a passion. |

You have to understand what Ruby is. It is not a language. It is 5 |
| 31 |
languages. Like python27 and python3 are really different languages with |
| 32 |
much in common. The difference is the python devs have solid reasons for |
| 33 |
doing python3 and the transition has been mostly smooth. Each new minor |
| 34 |
version of ruby is a whole new language and the devs are OK with large |
| 35 |
breaking changes between minor version numbers. |
| 36 |
|
| 37 |
So why 3 rubys? Because they are 3 languages and you have packages that |
| 38 |
for whatever reason are tied to different rubys. Just pretend to |
| 39 |
yourself that they aren't really ruby22, ruby23 and ruby24 - they are |
| 40 |
php, perl and python (or whatever 3 language names you like that help |
| 41 |
you get past the 3 rubys! thing). |
| 42 |
|
| 43 |
You probably need all 3. As housekeeping, you can put this in make.conf: |
| 44 |
RUBY_TARGETS="ruby22", |
| 45 |
and remove all ruby versions from world |
| 46 |
and let depclean, revdep-rebuild and emerge world take care of the details. |
