Comment 2 for bug 519670

As far as I can tell, the gtkdocize tool generates a makefile that doesn't work right from a build directory. The way it's all set up, if you run the configure in the source directory, then cd into libudev/docs and run make there, you'll get correct documentation files... but only if you don't modify the gtk-doc.make with the sed statement in the debian/rules 'prep' target. After that, a make distclean will actually leave those generated documents where they are. For what it's worth, I'd add an extra step to the build to have it do that just to get them right. I'll see if I can write a patch for it.
