python-numpy / cross compile badness

dear list,

i'm having problems building opencv with current oe. the point of
failure is python-numpy with "CROSS COMPILE Badness: /usr/include in
INCLUDEPATH: /usr/include"

i managed to remove the usr/include from the compiler command when
investigating a couple of days ago, but there were further problems down
the road.

my host system is running gcc (and friends) 4.5.2 and i suspect that the
error above is a result of using this specific version when compiling
gcc-cross*, since i could build without any problems on another system
with gcc 4.4.1. unfortunately that system was 64bit so i cannot use the

Build Configuration:
BB_VERSION = "1.12.0"
METADATA_BRANCH = "2011.03-maintenance"
TARGET_OS = "linux-gnueabi"
MACHINE = "beagleboard"
DISTRO = "angstrom"
DISTRO_VERSION = "2011.03"
TARGET_FPU = "hard"

thanks for any pointers, cheers, opt
