Yes, there are several perls available for this hardware. Which one works for you will depend on the specific hardware and os platform you're running.

For work with the PocketPc os you can use PerlCE 5.8.0 or Perl 5.6 for CE. I have personally used this on my ipaq pocketpc.

For linux based systems, perl is probably available as a pkg to install. I have used the familiar embedded linux (which is debian based) on both an intrinsyc cerfcube and on an ipaq pocketpc.

HTH!
