Problem with gem installing

I am using Aptana RadRail framework. Some times, after installing and
trying to use new gem i getting error like this

c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in
gem_original_require': no such file to load -- soap4r (LoadError) from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:inrequire’
from main.rb:12

Also problem happens with nokogiri and zlib

It happens with diferent gems(but not with all). Also it depend from
machine - done at one and error at another(machines have equals programs
installed). Of course, i checked property “Installed interprenters”.
Fount no help from google.

Thanks!

Did you try to require ‘rubygems’ before requiring your other gems?

Of course, i try it… Also i try to add new system variable, that added
rubygems every time i start project - nothing helps me=(

p.s. i use ruby version 1.86 and latest versions of these gems

Maybe the dependency spec in gem description is incomplete. Try to
install the missing package first.

I encountered similar problem when I try to install rails right after
ruby installation.
