Subject: Can't do "gem update --system" - libcrypto.so.4: cannot open shared 	object file: No such file or directory - /usr/local/lib/ruby/1.8/i686-linux/digest/md5.so 	(LoadError)

Hi,

I've update the software on my linux box ( v4 to v5.0
http://clarkconnect.com/ ) upgrade something has gone screwy with my
Ruby installation on the machine. Any ideas?

My ruby/rails installation was working fine until I did the Linux
update.  Gem Update Affected (not that the 'md5.so' is actually there
in the directory)
