Absolute Pressure and Temperature Sensor - BMP085

Can anyone help with this?  The set up is  "ArduIMU+ V2 (Flat)" with the

 "Absolute Pressure and Temperature Sensor - BMP085" and  

 "HMC5843 - Triple Axis Magnetometer Rev 1.2" all from the store.

The two sensor boards are stacked on header pins soldered to the I2C port of the imu board.

Used "ArduIMU_1.8.2.zip"  to test the hardware.   Tested each of the sensors individually and ran the imu code.  The mag. board readings appear to be correct.

Using the "APM_BMP085/.../APM_BMP085_test.pde"  library code the  BMP085 board returns "Pressure:0 Temperature:0.00 Altitude:44330.00" repeatedly.    Do the  XCLR and EOC pins need to be connected? 

Haven't removed the mag. board yet to test there's an I2C address conflict.  Wanted to ask before desoldering.
