Re: pkg/53751: code blocks fails to build

Seems that one of the many benefits of the pkgsrc system is that a library or sub-component which is used in multiple packages only needs to be built once for use by all, but this can also be an Achilles Heel.  If the library or sub-component is upgraded and the API or similar isn't kept backwards compatible then some packages which rely on it that haven't upgraded may become unbuildable and unusable.  Is there an option in the pkgsrc system that permits a package to import and build it's own local copy of an older library or sub-component that it depends upon?  If so that might solve the problem with Codeblocks without having to move wxGTK back to GTK2, at least until Codeblocks is upgraded to use the wxGTK/GTK3 interface.

However, in this case the real source of the problem may be in wxGTK rather than in Codeblocks as Codeblocks can be build and linked with wxGTK that was built with GTK3, but at run time it complains that GTK2 and GTK3 symbols can't both be in the same image.  It would seem that if wxGTK can build with both than shouldn't it be intelligent enough to know which GTK calls it should be using?
