manually compiling ruby 1.8.7 on ubuntu hardy

running two rails 2.3.8 apps on two virtual servers in ubuntu 8.04 with apache and passenger. the ruby version is 1.8.6

we are upgrading one of the apps to rails 3.0.4. my understanding is that we need ruby 1.8.7 to run the app. with this version of ubuntu we will need to compile ruby 1.8.7 manually.

1. never compiled manually before. if you know of any resources i should check out that would be great.
2. i have not been able to determine the vers开发者_StackOverflowion of passenger and am trying to make sure it will be compatible with rails 3.0.4. any suggestions?
3. the application we are leaving in 2.3.8 is our core business application and i need to make sure i don't mess it up.

Thanks!

Just use RVM. Almost everybody use it now.

Early Passenger versions for Apache had some bugs so my suggestion is to simply upgrade Passenger to the newest version.
