Gem_original_require zlib problem

I’m trying to just to a first time install of gems (and net/ssh ) in
particular… and I can’t even do a

gem update --system

I get the following dump (any idea how to fix this?)

/usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in

I had a similar error in Ubuntu, but I think I fixed it by making sure
I had the development libraries for compression. That was a while
ago, so I can’t recall exactly how I fixed it.

If you built ruby itself from source, this means that the zlib extension
wasn’t built at that time. This in turn probably means that you didn’t
have the zlib development headers installed at the time.

Check you have a package called something like ‘zlib-devel’ and rebuild
ruby.

I have been wrestling with this issue as well. How do I check for a
package, and if I don’t have it, then what do i do?

It appears that we were able to finally get Ruby to bind to the openssl
through rebuilding a couple of different configurations on SUSE Linux
10.

Thanks for all the pointers.

Depends on what platform you’re using. For example:

On CentOS:
rpm -qa | grep zlib
yum install zlib-devel

On Ubuntu:
dpkg-query -l | grep zlib
apt-get install zlib1g-dev

or something like that - I don’t have an Ubuntu box handy right now
