graphics/opencv ISSUE with gcc 4.6.3

[awarecons]

UPD:

with gcc 4.2.1 and libIlm (OpenEXR) compiled with gcc 4.6.3

opencv-2.3.1_5 -> opencv-2.3.1_6
...

Stop in /usr/ports/graphics/opencv/work/OpenCV-2.3.1.
*** Error code 1

Is that possible to make it compile with gcc 4.6.3?

Thank you in advance.
