Buffer error while executing gem

ruby-talk
1

Hello,

when running on Windows XP gem.exe which comes with Ruby 1.8.5, I get
the following error:

H:\>C:\ruby185\bin\gem install net-ssh
Bulk updating Gem source index for: http://gems.rubyforge.org
Install required dependency needle? [Yn]
ERROR: While executing gem ... (Zlib::BufError)
    buffer error

What could be the reason? Here is my gem environment:

H:\>C:\ruby185\bin\gem environment
RubyGems Environment:
  - VERSION: 0.9.2 (0.9.2)
  - INSTALLATION DIRECTORY: C:/ruby185/lib/ruby/gems/1.8
  - GEM PATH:
     - C:/ruby185/lib/ruby/gems/1.8
  - REMOTE SOURCES:
     - http://gems.rubyforge.org

I tried to update gem from 0.9.2 to 0.9.3. My state of the system
*before*
the update was this:

H:\>C:\ruby185\bin\gem environment
RubyGems Environment:
  - VERSION: 0.9.2 (0.9.2)
  - INSTALLATION DIRECTORY: C:/ruby185/lib/ruby/gems/1.8
  - GEM PATH:
     - C:/ruby185/lib/ruby/gems/1.8
  - REMOTE SOURCES:
     - http://gems.rubyforge.org

Here is how I performed the update; please note the error message:

H:\>gem update --system
Updating RubyGems...
Need to update 6 gems from http://gems.rubyforge.org
......
complete
Attempting remote update of rubygems-update
Successfully installed rubygems-update-0.9.3
Updating version of RubyGems to 0.9.3
Installing RubyGems 0.9.3
Error opening script file: setup.rb (Das System kann die angegebene
Datei nicht
finden)
RubyGems system software updated

After the update, there was no file 'gem.bat' in my ruby/bin directory -
only a shell script file named "gem". Next, I tried to do a manual
install:
I downloaded the zip file for gem 0.9.3, unpacked, and executed in this
directory:

  ruby setup.rb all

which resulted in:

....
install sha1.rb c:/ruby185/lib/ruby/site_ruby/1.8/rubygems/digest
install sha2.rb c:/ruby185/lib/ruby/site_ruby/1.8/rubygems/digest
<--- lib/rubygems/digest
<--- lib/rubygems
<--- lib
hook H:/dl/lang/rubygems-0.9.3/./post-install.rb failed:
undefined method `file_name' for #<Gem::Specification:0x2e47648>
Try 'ruby setup.rb --help' for detailed usage.

Now, despite the error, I *do* have a gem.bat in my bin directory,
and at first sight it seems to work as expected; but I still wonder
whether this error could cause problems in the future.
