having trouble installing rubygems

[nhammet]

To warn: I am new to Ruby, I have installed ruby-1.8.7 in /usr/local/bin on a linux box running centos, but get the following error(s) after attempting to install rubygems per published instructions:

/usr/local/lib/ruby/1.8/yaml.rb:9:in `require': no such file to load -- stringio (LoadError)
from /usr/local/lib/ruby/1.8/yaml.rb:9
from /home/nhammet/rubygems-1.3.1/lib/rubygems/config_file.rb:7:in `require'
from /home/nhammet/rubygems-1.3.1/lib/rubygems/config_file.rb:7
from /home/nhammet/rubygems-1.3.1/lib/rubygems.rb:882:in `require'
from /home/nhammet/rubygems-1.3.1/lib/rubygems.rb:882
from setup.rb:22:in `require'
from setup.rb:22

I looked at line22 and it says that it requires 'rubygems' but I know that and it isn't installed yet. Is there some missing step here? Something in my unix env? Do I need a LOAD_PATH env variable set?

Any help at all or pointers would be appreciated.
FYI -
I installed ruby
with ./configure
make test
sudo make install #(since not root and needed this in /usr/local)

Thanks

Hello Everyone,

Sometimes just askiing a question helps... motivates me to finally find it.

to solve my problem I did 2 things.

1. revisit my install of zlib (ala zlib-1.2.3)
and use the following to install zlib in /usr/local/lib:

./configure -s
make
sudo make install

(the above makes sure the shared libraries are installed... I didn't figure it out, it was thanks to 'google')

2. in ext subdirectory from ruby-root directory, in Setup, uncommented everything except apparent Windows-centric items, and re-installed ruby-1.8.7.

./configure
make
make test
sudo make install.

Then I was finally able to run :

ruby setup.rb # (in my rubygems-1.3.1 root directory)

Viola!

Hope this helps others...
