I am unable to install rails via the CLI, Fedora 13. This is a new  
installation and I am not certain why I am receiving this error.

ERROR: Loading command: install (LoadError)  
no such file to load – zlib

You would get a pretty good idea by googling that last line.

Thanks for the smack in the noggen. My laptop blew up mid installation  
and I have been rebuilding everything all day.

zlib wasn’t found so I had to re-make so to speak. Rails is humming  
along, back to the project.

cheers
