zlib-devel without root privilage

Hi i have problem with zlib-devel (problem with "gem install rails"), i compiled zlib, but i dont ktow how to provide ruby zlib-dev dependency. In subject i mention - i dont have root privilage :confused:

I don't know of any way offhand to install Ubuntu packages without root access - you should probably get your sysadmin and/or hosting provider to install the package.
