There might be a check somewhere not only for the EUID, but also for the UID. Try setting $< = 0, or by using POSIX::setuid.

Having said that, you may want to get rid of perl-suid, as it has been deprecated for some time, and gotten rid of in 5.12. You're probably better of either using sudo, or putting the appropriate magic in your /etc/fstab so a file system can be mounted by a non-root user. For instance, on my home boxes, I have: 

/dev/sdb1      /mnt/sdb1     auto    use    0 0
/dev/sdb2      /mnt/sdb2     auto    user   0 0

in my /etc/fstab file, allowing a non-root user to mount usb devices.
