The perl compiler is included with the perl distribution starting with
5.005. However, it doesn't work. I tried using it because I had a
really long script that took several seconds to compile on the fly, just
to speed things up. Dunno where the trouble lies, but I was warned by
the docs that dragons lived in that part of the world... Best solution
I think would be just for you to chmod the thing to 711 so only owner
has permissions to read/write but everyone has permission to execute.
You could xor-encrypt the perl source and write a C program that
decrypts and interprets it at the same time (may need to use the
binfmt_misc feature of the kernel to do it).

True, very true. Speeds up development and debugging substantially.
Enables you to fix bugs on the fly. Used it to advantage for all of my
perl projects.
