Support for the "p4 move" command was added in 8e9497c (git p4:
add support for 'p4 move' in P4Submit, 2012-07-12), which checks
to make sure the client and server support the command.
But older versions of p4d may not handle the "-k" argument, and
newer p4d allow disabling "p4 move" with a configurable. Check
for both these cases by testing a p4 move command on bogus
filenames and looking for strings in the error messages.

Gary explained how to administratively disable "p4 move". This
patch checks for that condition, and "p4 move -k", which is
missing in p4d 2009.1.
I'm not super happy with it, due to the string-searching in the
error messages. But I can't think of a better way: if "p4 move
-k src dest" returns 1, is it because the server doesn't support
it? arguments were wrong? printer on fire?
Vitor, can you test that it works for you? It's probably worth
putting in the code just so no one else finds the same mysterious
failure.
