=v= If the issue is that you've upgraded to Perl 6, you can put
something like this in your .bashrc or similar startup file:
Or for csh users:
setenv PERL6OPT '-M-warnings=deprecated'
It would be PERL5OPT if you're using a particularly recent
version of Perl 5 instead of Perl 6.
=v= This is the quickest way to turn off deprecation errors
BUT BEWARE that they'll be turned off for as long as you leave
the line sitting in your .bashrc (possibly years and years,
which wouldn't be a good idea at all).
