Subject: LoadError - Mechanize, Hpricot (gems)

Hello,

I've been trying to install and use Mechanize ( http://rubyforge.org/projects/mechanize/
), and cannot solve the errors that occur.

Actually, I'm not sure the error is really linked to this gem, because
I remember having had the same kind of problems while trying to
install other gems.

So, I'm working on windows, with cygwin.

I installed Mechanize with the following command line :

> gem install mechanize

and it seems to have installed successfully :

Successfully installed mechanize-0.6.10
Installing ri documentation for mechanize-0.6.10...
Installing RDoc documentation for mechanize-0.6.10...

So, after this, I try to use it, as written on this page :

http://mechanize.rubyforge.org/mechanize/files/EXAMPLES_txt.html

And here's what happens :

irb(main):001:0> require "rubygems"
=> true
irb(main):002:0> require "mechanize"
LoadError: Permission denied - /usr/lib/ruby/gems/1.8/gems/hpricot-0.6-

32:in `require'
        from (irb):2
        from /usr/lib/ruby/site_ruby/1.8/rubygems/source_index.rb:279

Then, I just go where the hpricot_scan.so file is, "chmod +x" it, and
retry. Then :

irb(main):003:0> require "mechanize"
LoadError: No such file or directory - /usr/lib/ruby/gems/1.8/gems/

32:in `require'
        from (irb):3
        from /usr/lib/ruby/site_ruby/1.8/rubygems/source_index.rb:279

Anyway, the file really does exists.

Is there anyone who know how to solve this problem please ?
