It looks like Patrick's files were [somewhat] based on newer files.

Try removing these lines from "packages/packages":

  package CYGPKG_HAL_ARM_CL7211 {
          alias           { "Cirrus Logic CL7211 evaluation board support" hal_arm_cl7211 arm_cl7211_hal }
          directory       hal/arm/cl7211
          include_dir     cyg/hal

Let me know if you continue to have problems.
