Gem_original_require zlib problem

ruby-talk
1

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
`gem_original_require': no such file to load -- zlib (LoadError)
        from

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?

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

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.
