Problems installing OpenCV on Debian Stable

["aej" <axel.e.jensen@gmail.com>]

Hi
Im trying to install OpenCV on a debian-2.6.8-3-386, stable, which
seems to go ok.
But when Im trying to compile OpenCV programs I get this error:

" make
g++ `pkg-config opencv --cflags` -Wall -c eksempel1.cc
Package opencv was not found in the pkg-config search path.
Perhaps you should add the directory containing `opencv.pc'
to the PKG_CONFIG_PATH environment variable
