looking for a part

I'm trying to find a tiny smd connector I can use to stack two small boards.

preferably something with an eagle library.

I was thinking of something like this Transceiver nRF2401A with Trace Antenna Connector - WRL-00561 - SparkFun Electronics

but I need both the male and female parts, can anyone point me to something?

These are fairly standard parts. I have not looked for the 2mm parts like those you reference at digikey, but the more common .1" headers (as found on the arduino) are available in surface mount options, both male and female types.

Spend some time with Digikey's web site/catalog/search function and you'll find them.
