OK, I still I do not have RT 3.0.4 working on RedHat 9. This is what I
-Set locale to C
-Rebuild Perl without threading from SRPM
-Installed latest versions of necessary modules
-Rebuilt and installed fresh Perl (stable 5.8.0).
Of course, before this I followed all steps to make RT work on red Hat 9
(rebuilt mod_perl etc…)
And still I have same error.
