The docs may be right, but 5.011 works for me (on 5.20):

$ cat xxx.pl
#!/usr/bin/env perl 
use 5.011;
use warnings;

$x = 1;
$ ./xxx.pl
Global symbol "$x" requires explicit package name at ./xxx.pl line 5.
Execution of ./xxx.pl aborted due to compilation errors.

That said, I see no great advantage to having a non-stable-release version as the minimum requirement, especially such an old one. YMMV.
