I have had this error in both my manual installation of Ruby and Rails as well

Hi Luis,
I am hard-wired into a 30Mbps connection, and I uninstalled
and reinstalled 1.3.4 on 186-26 probably five different
times and tried updating a few different gems each time,
including some which had nothing to update. Each time I got
that same set of debug messages.

Thank you Bob,
Maybe the Zlib error was triggered due a corrupt file download, since the Rails
gems are not small and RubyGems uses open-uri which doesn't guarantee too much
file integrity.
Have seen similar issues over slow network connections.

Just checked - rubygems 1.3.4 is fine under One-Click
Installer 186-27 (RC2).
I rolled back to rubygems 1.3.3 under One-Click Installer
186-26 (Stable), and everything works fine there, too.

Hello Bob,
Can you confirm this happens with One-Click Installer 186-27? (RC2).
Also, 64bits prompt do not play nice with 32bits processes, but I believe that
is not the issue here.
