I've installed OpenCV image processing library and when I try to install
opencv gem(using gem install opencv) for ruby I get the following error
when building the library

iplimage.cpp: In function 'VALUE mOpenCV::cIplImage::rb_initialize(int,
VALUE*, VALUE)':
iplimage.cpp:91: error: 'cvCvToIplDepth' was not declared in this scope
iplimage.cpp: In function 'VALUE mOpenCV::cIplImage::new_object(int,
int, int)':
iplimage.cpp:228: error: 'cvCvToIplDepth' was not declared in this scope
iplimage.cpp: In function 'VALUE mOpenCV::cIplImage::new_object(CvSize,
int)':
iplimage.cpp:234: error: 'cvCvToIplDepth' was not declared in this scope

has anybody managed to use opencv for ruby?
