Can't locate I18N/LangTags/ in @INC in Settings Tab

Using RT 3.8.9 and Perl 5.8.8 on Solaris 10 x86.
I just finished installing through an upgrade. In the Preferences Section in
the Settings Tab, there is no save button and just an error at the bottom of
the page.

Can’t locate I18N/LangTags/ in @INC (@INC contains:
/opt/rt3/bin/…/local/lib /opt/rt3/bin/…/lib

/opt/rt3/bin/…/lib/RT/ line 666.

I went to my perl and tried to install I18N:LangTags but it said it was up
to date. How can I fix this? or at least get the save button to show up?
