Command line install of topojson throwing fatal error

Question

I'm trying to install topojson on OSX Maverick and I'm getting a fatal error: fatal error: 'sys/types.h' file not found. I include below what leads up to the error in the terminal and then everything that follows.

I just installed node.js specifically for this - so I'm not sure which package the issue is related to.

I did use sudo: sudo npm install -g topojson. I am by no means an expert at command line.

Jeff was right - thanks Jeff - seems like I just needed to make sure my xcode was updated. Actually, I discovered that I needed to reinstall xcode after I updated to Maverick. I didn't expect that.

Sorry, tak3r - thought I had posted this last week!
