Eagle question

Hello -

I’m looking at using SeeedStudio for an open source project. Its my first PCB board. Thankfully its only a few parts. I’ve built the circuit I adapted and it works just fine. Its based on the JouleThief [google it].

I’ve laid out the schematic in eagle. Everything is fine there too. When I go to build the board, I notice that the LED shape in a rectangle. I was looking at using a 5mm round led. Any idea why Eagle would use a rectangular shape in the board layout when I specified a regular 5mm led in the schematic?
