That's right. From the man page:
mhical supports only a very limited subset of RRULE formats.
Specifically, only a frequency of YEARLY and an interval of 1 are
supported.

Sure, that would be great! The code that parses that YEARLY format
is currently in rrule_clock() in sbr/datetime.c. Though maybe it
would be better off in the ical parser.
