Dear Marco,

Thanks for reply.

I am happy to link dynamically, but I got the requirements to provide
both static and dynamic version.

Maybe I can submit "request for improvement" for libxml2? It looks like
*.a was simply not included into package, so I hope it is trivial to fix it.

Yes, it is possible to explore the library this way, but I think
"GraphicsMagick++-config --libs" should report, which library was used
to produce libGraphicsMagick.a. I can't use "-lpng", and I can't any
other alternative like "-lpng12" or "-lpng14", because I may end up with
missed symbols in libGraphicsMagick.a.

In this case everything looks good :)

I agree.
