Every time I try to update to exim 4.68 it throws back this error whether updating manually through /scripts/eximup or doing it through WHM.

exim-4.68-1_cpanel_maildir.i386.rpm is not a valid rpm file at /scripts/eximup line 276.

Figured I'd grab the rpm and try to manually push it to see why it was failing;
error: Failed dependencies:
perl(SafeFile) is needed by exim-4.68-1_cpanel_maildir.i386

And.. now I'm kinda stuck as to what to do or why exim won't update to 4.68 =/
