openvrml-0.18.3 libxml2 required to build

[miyasita@…]

I tried to install OpenVRML, but the port command stopped with error:

% sudo port install openvrml

I thought that openvrml port needs libxml2 port. I added "port:libxml2" into the Portfile of openvrml (see the following patch file) and I succeed to install openvrml.

In addition, I had to overcome another bug(?) in the sources of openvrml. I had to add "#include <boost/function/function0.hpp>" into src/libopenvrml/openvrml/scene.h with the following patch:

But this patch must go to openvrml developers.

Replying to miyasita@…:

Sorry, I obviously forgot to declare a dependency on libxml2.

In addition, I had to overcome another bug(?) in the sources of openvrml. I had to add "#include <boost/function/function0.hpp>" into src/libopenvrml/openvrml/scene.h

This seems to be caused by a change in boost-1.40.0. The OpenVRML developers already fixed this problem for future versions of OpenVRML. In the meantime, we can use your patch. The patch file and a patch for the portfile is attached.

I'm the maintainer of this port. Can anybody with commit rights please commit my changes and close this ticket?
