Error While RUnning Rails 2.0.2

Hi Friends,

    I had a Rails 2.0.2 application but while running the

application using script/server i am getting the below error.

hp@ubuntu:~/giftgenius$ script/server
internal:lib/rubygems/custom_require:29:in require': no such file to load -- script/../config/boot (LoadError) from <internal:lib/rubygems/custom_require>:29:inrequire’
from script/server:3:in `’

I have installed rails 2.0.2 gem in my system but still it doesn’t
works. Anyone please help me to resolve this issue…

Thanks in Advance…
