This function:

https://github.com/libguestfs/libguestfs/blob/4aa4edf972bc8df8869cdcaa4ab4f40b63a626cf/daemon/yara.c#L308

returns 1 if HAVE_YARA is defined.  This is defined by this
./configure test:

https://github.com/libguestfs/libguestfs/blob/4aa4edf972bc8df8869cdcaa4ab4f40b63a626cf/m4/guestfs-daemon.m4#L128

In other words it depends how libguestfs was configured.  Where
did you get libguestfs from?  How was it compiled?

Rich.
