I did some study on the Perl's ecology of XS system. It seems an typemap can be shared only if its author made it using ExtUtils::Typemap as a module. I also found that Cairo's main typemap is auto-generated at pre-compilation stage of the module.

So it seems I cannot use the existing Cairo wrapper to cooperate with the wrapper of my lib. I would consider a re-design of my API to allow it working without using Cairo's types as function parameter, like this: 

typedef enum
{
    SURFACE_PDF,
    SURFACE_SVG,
    SURFACE_IMAGE,
    SURFACE_PS
} SurfaceType;

class MyPage
{
    MyPage(SurfaceType type);
};
