wpsd crashes on Yosemite
Since wpsd and /usr/local/bin do not ship with OS X out of the box, you'd need to look at the creation date of the file and or check your backups to determine when the file arrived.

You could run the strings command against the file and see if that sheds any light on the process, but we might need to know more about how you install open source tools and/or add software to the system (or look at the whole dump) to know what the tool does.
