I assume you mean the 'Too late for "-T" option at script.pl line 1.' error.
This happens because you have run perl without -T, then when it examines the #! line
and sees -T, it realizes you want tainting, but it is too late. You need to make sure -T is
passed when using 'perl script.pl'. I know of no way around this, as opposed to aliasing 'perl'
with 'perl -T' or some similar lunacy.
