Hi,

We are running RE:

ruby 1.8.7 (2009-06-12 patchlevel 174) [sparc-solaris2.10], MBARI
0x8770, Ruby Enterprise Edition 2009.10

I tried a simple web app with a controller rendering a text and is
working in my PC but on the server I get:

Error message:
undefined method `alias_method_chain' for
I18n::Backend::Simple:Class
Exception class:
NoMethodError

I had a look in activesupport-2.3.4/lib/active_support/vendor/
i18n-0.1.3/lib/i18n/backend/simple.rb and there is not any
alias_method_chain method.

How can I solve this issue?

From the sys admin:

"It had updated the gem packages to start using 2.3.5 instead of 2.3.4
and the LD_LIBRAY_PATH variable was not set correctly."
