Errors compiling FreeIMU examples for the MS561101 sensor

I'm trying to compile MS561101BA_altitude under examples in the FreeIMU-20121106_1321 library found http://www.varesano.net/projects/hardware/FreeIMU I get the following errors (see below) Can someone point me in the right direction?

MS561101BA_altitude:35: error: 'MS561101BA' does not name a type MS561101BA_altitude.pde: In function 'void setup()': MS561101BA_altitude:50: error: 'baro' was not declared in this scope MS561101BA_altitude:50: error: 'MS561101BA_ADDR_CSB_LOW' was not declared in this scope MS561101BA_altitude:55: error: 'MS561101BA_OSR_4096' was not declared in this scope MS561101BA_altitude.pde: In function 'void loop()': MS561101BA_altitude:61: error: 'baro' was not declared in this scope MS561101BA_altitude:61: error: 'MS561101BA_OSR_4096' was not declared in this scope

That example compiled fine for me.

Did you put the MS561101BA library in Arduino/libraries/MS561101BA? You can't leave the libraries buried in the FreeIMU-20121106_1321/libraries folder.
