[Dovecot] automatically compiling sieve scripts

Without having looked into the code: Does Pigeonhole automatically compile a sieve script if the compiled form is not /strictly/ newer than the text form? I'm running into the problem that during automatic installation of a global sieve-after script, my Makefile has a rule to compile, yet afterwards, the sieve plugin complains about not being able to compile (which is correct, but it shouldn't try in the first place). Both text and binary form have identical time stamps. I don't want to sleep between install and sievec.
