hi i have installed ruby 1.9.1 side by side with previously installed  
ruby 1.8.7  
i have created symlink to ruby1.9 also.  
now when i say ‘gem1.8 list’, it shows the list of gems installed for  
ruby 1.8

i’ve not installed any gems for ruby 1.9.1 yet.  
problem is when i try to get list of gems for ruby1.9.like:  
$ gem1.9 list

following error comes :

/usr/lib/ruby1.9/1.9.1/rubygems/spec\_fetcher.rb:1:in `require': no such file to load -- zlib (LoadError) from /usr/lib/ruby1.9/1.9.1/rubygems/spec_fetcher.rb:1:in`\<top

from /usr/bin/gem1.9:24:in `’

and when i tried to install gems for ruby1.9:  
$ sudo gem1.9 install activesupport

following error comes:

/usr/lib/ruby1.9/1.9.1/rubygems/package.rb:10:in `require': no such file to load -- zlib (LoadError) from /usr/lib/ruby1.9/1.9.1/rubygems/package.rb:10:in`\<top (required)\>’

Dear Abhishek,

> file to load – zlib (LoadError)

your system has a problem finding zlib …  
there have been quite a number of threads investigating this problem  
with  
various versions of Ruby on this list.  
What OS are you using and how did you install Ruby 1.9 ?

Best regards,

Axel

i’m using ubuntu 9.04  
i’ve followed following steps to install ruby 1.9.1

1. i,ve downloaded ruby 1.9.1-p243 from  
“[Download Ruby](http://www.ruby-lang.org/en/downloads/)”
2. extract that .tar.gz
3. run ‘./configure --prefix=/usr --program-suffix=1.9’
4. run ‘sudo make && sudo make install’
5. create symlink ‘ruby’ to ‘ruby1.9’
