Fix for CentOS “Can’t do setuid (cannot exec sperl)”

If you are running a Perl script with the setuid bit, it actually runs a slightly modified version of Perl so that it is a bit more cautious. On a CentOS box, you need to install the ‘perl-suidperl’ package to get the necessary files installed. Otherwise you get an error like this:

[root@host bin]# ls -al myscript.pl
-rws--S--- 1 mail mail 1218 Oct  1 13:09 myscript.pl

[root@host bin]# ./myscript.pl
Can't do setuid (cannot exec sperl)
