no worries! i'm tired and spread kinda thin at the moment :)

yes, i ensured that the file and directory exist ahead of time:

$ ls -l /var/log/ |grep influx && ls -l /var/log/influxdb/
drwxr-xr-x  2 root  wheel         512 Mar 21 21:21 influxdb
total 0
-rw-r--r--  1 root  wheel  0 Mar 21 21:21 influxd.log

sure thing.

syslogd.conf (once i get this working i plan on moving relevant bits to 
/etc/syslog.d/influx.conf):

#    Spaces ARE valid field separators in this file. However,
#    other *nix-like systems still insist on using tabs as field
#    separators. If you are sharing this file between systems, you
#    may want to use only tabs as field separators here.
#    Consult the syslog.conf(5) manpage.
