Hi,

and sorry if this has been asked before - couldn’t find a good solution  
for the following problem yet…

I can’t get some of my gems to work and I know there has been trouble  
with this and Leopard before - but first things first:

I have ruby, rails and rubygems installed on my Mac, running 10.5.  
Previously, I had troubles since for ruby was also installed via  
MacPorts (I am sure I had a reason for that…) - so ruby is located  
both in /usr/local/bin and /opt/local/bin.

‘which ruby’ shows that '/usr/local/bin is used, so that’s fine

‘gem environment’ shows  
RubyGems Environment:

- RUBYGEMS VERSION: 1.1.1
- RUBY VERSION: 1.8.6 (2007-03-13 patchlevel 0) [universal-darwin8.0]
- INSTALLATION DIRECTORY: /usr/local/lib/ruby/gems/1.8
- RUBY EXECUTABLE: /usr/local/bin/ruby

and lo and behold, that’s were I find the gem that I can’t get to work.

However, if I run a script requiring that gem, it returns the following  
message:

/usr/local/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:27:in  
`gem_original_require': no such file to load -- ensembl-api (LoadError) from /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in`require’

I am not too familier with the exact folder structure that ruby uses,  
but something is fishy here regardless.

Any help would be greatly appreciated

/Marc

Don’t know if this will be any help, but here’s mine, using the standard  
ruby that is present on Leopard already:

- RUBYGEMS VERSION: 1.2.0
- RUBY VERSION: 1.8.6 (2008-03-03 patchlevel 114)  
[universal-darwin9.0]
- INSTALLATION DIRECTORY: /Library/Ruby/Gems/1.8
- RUBY EXECUTABLE:  
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby
- EXECUTABLE DIRECTORY: /usr/bin
- RUBYGEMS PLATFORMS:
  - ruby
  - universal-darwin-9

- GEM PATHS:
  - /Library/Ruby/Gems/1.8
  - 

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems  
/1.8

and the standard one in /usr/bin ? Or did you remove that? You might  
want to consolidate.

lucky for you I have every gem sitting on my hard drive in  
tarballs… 🙂

you’re requiring the gem name. require is still just require in ruby,  
it loads files:

ensembl-api-0.9/lib/  
ensembl-api-0.9/lib/ensembl/  
ensembl-api-0.9/lib/ensembl/core/  
ensembl-api-0.9/lib/ensembl/core/activerecord.rb  
ensembl-api-0.9/lib/ensembl/core/project.rb  
ensembl-api-0.9/lib/ensembl/core/slice.rb  
ensembl-api-0.9/lib/ensembl/core/transcript.rb  
ensembl-api-0.9/lib/ensembl/core/transform.rb  
ensembl-api-0.9/lib/ensembl/db\_connection.rb  
ensembl-api-0.9/lib/ensembl.rb

so you probably want:

```
 require "ensembl"
```
