You did not have zlibc installed at the time you compiled/installed 
ruby. This caused ruby to not have zlibc which is required in order to 
install rubygems.

Solution:

1. install zlibc (apt-get install zlibc)
2. recompile/reinstall ruby (zlibc must be installed when you do this)
3. install rubygems
