No, no configuration file, your system will execute whichever perl version it encounters first in your path (or the one you explicitly specify). Check your $PATH with

echo $PATH

, if /usr/local/bin appears before /usr/bin you can get away with creating a symlink from /usr/local/bin/perl to your new perl executable. That way you can call the new version with perl or /usr/local/bin/perl or call the older version with /usr/bin/perl. You may get confusing behaviour if you do that though, because scripts and/or libraries may call a different version of perl than you're expecting.


Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it. -- Brian W. Kernighan
