Looks good to me. What port is this a dependency for?

Update to 0.6.3

Use multi distfiles approach D8837, D8864, D8865 are no more needed to be land

@mat It's another approach which do not use multiple distfiles and do not build required dependencies into ${WRKSRC} at once.

@swills I need it as build dependency for a port I will bring into the port tree. As It's a library, it's useful to have a separate ports/package for it like that it could be reused in case another port need it.

@mat Fixed! Thank you

Do not modify svn property
