ossec-agentd is unable to unmerge files

[ddpbsd]

On a new agent installation of 2.9rc1, I get the following errors:

2016/06/20 16:09:28 ossec-agentd: ERROR: Unable to unmerge file '/etc/shared/cis_rhel_linux_rcl.txt'.

I believe these files are installed read only (440):

install -m 0440 -o root -g ${OSSEC_GROUP} rootcheck/db/*.txt ${PREFIX}/etc/shared/

Should this be changed to 640?
