This may be as simple as the order in which you have built your partitions.
OSX is trying to mount the Linux boot (where the bootloader is stored)
partition, correct? If the boot partition lies above the OSX partition, then
it should not see it.
Reformat your drive so that the partitions are as follows:
a - boot partition
b - swap
c - /root, /home, etc.
d - osx
It is possible the YDL installer will swap the bottom 2 around, but as long as
the boot partition is above the OSX partition. This should help (I hope :)
