Nicholas,
There was a fix to the hokuyo_node for OS X discussed a couple of
months ago on the mailing list. I'm not sure it was pushed into the trunk.
It was related to setting file opening flags for the hokuyo serial device
correctly.
I dont think it relates to your problem but you will be needing it anyway
to get the hokuyo to work on OS X.

[ros-users] In dynamic_reconfigure: an error (OSX)
Trying to build hokuyo_node on OSX, I get an error that I traced back to
dynamic_reconfigure.
Somehow cmake is generating spurious python dependencies (see below). The
problem is that a binary .egg file is identified as a dependency, but it
is treaded like a folder. So the .egg file exists, but is not a folder,
and when make tries to look into the folder that doesn't exist, it can't
find the file. But the .egg file works just fine, as shown below (import
works just fine in Python).
I'm not sure how to debug this, and I'm not sure how it can be fixed. Does
anyone with more experience with Python and CMake have any ideas?
