Subject: Gems and Ruby1.9 issues

Hello,

I setup ruby1.9 on a FreeBSD server's home directory successfully. Then
I setup my GEM_HOME in my environment and installed the required gems
for the script I've wrote, which are twitter and ya2yaml.

When I try to run the script I get this error though, which does not
appear in my MacOSX desktop at home, where I'm using the same gems/ruby
version.

Here's the log:

---------------------------------------

For some reason "multi_json-0.0.5" seems to break. Is there anything I
can do to fix this?

best regards
