I’m trying to install a fresh copy of Ruby into empty directory  
‘/modlest/modlusr/ruby’ on a stock Red Hat server but it doesn’t work.  
Here’s what I’ve done:

/modlest/users/erik/rubygems-1.3.3\> cat /proc/version  
–\>Linux version 2.6.9-67.0.20.ELsmp  
(removed\_email\_address@domain.invalid) (gcc version 3.4.6 20060404  
(Red Hat 3.4.6-9)) #1 SMP Wed Jun 18 12:35:02 EDT 2008

/modlest/users/erik/ruby-1.8.7-p174\>./configure  
–prefix=/modlest/modlusr/ruby  
–\>everything went fine

/modlest/users/erik/ruby-1.8.7-p174\>make  
–\>everything went fine

/modlest/users/erik/ruby-1.8.7-p174\> make install

–\>/modlest/modlusr/ruby/gems

/modlest/users/erik/rubygems-1.3.3\> ruby setup.rb  
–prefix=/modlest/modlusr/ruby  
–\>all seems to go okay

/modlest/users/erik/rubygems-1.3.3\> which gem

/modlest/users/erik/rubygems-1.3.3\> gem  
–\>/modlest/modlusr/ruby/bin/gem:8:in `require’: no such file to load  
– rubygems (LoadError)  
–\> from /modlest/modlusr/ruby/bin/gem:8

This is driving me nuts, and any assistance would be greatly  
appreciated.

You shouldn’t be prefix’ing RubyGems installation, it should detect  
Ruby installation options and use them.

Can you create a pastie of the actual output where rubygems.rb is  
being copied?

(you didn’t include that, which could be a hint of what is going on)

Maybe an issue with environment? Could you try to define an EXPORT for  
gem  
on your shell profile?

I did a reinstall, this time _not_ including the prefix=, and that fixed  
it. Many thanks!
