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.
Neat related idea (and you know, I have princepawn to thank for making me think about this in the first place) -- you could also have a batch file (as you explained in the CB, you're worried about porting to win32), that calls perl.exe -T %1 (or however that's done =), call it (say) perlrun.bat, stick it in your PATH, and call the script as perlrun script.pl
