For everything I see, that should work.

In classes/image.bbclass, RDEPENDS is augmented by the contents of
IMAGE_INSTALL, LINGUAS_INSTALL, MULTILIB_IMAGE_INSTALL, and NORMAL_FEATURE_INSTALL.

The place to start looking for this is within the log.do_rootfs in the rootfs
directory you are working on.  You should see something that indicates it's
trying to install the "lib64-perl".  (in the case of RPM, it should eventually
rename it to "perl" -- but choose the 64-bit version.)
