Need a newer version of makeinfo

[Colin Percival]

Version 2.6 of Lilypond (print/lilypond) requires makeinfo version
4.7 or higher to build.  Makeinfo is in the base system, but only
as version 4.6 in existing releases (version 4.8 was imported into
HEAD two days ago).

Does anyone have any suggestions as to how this should be handled?
Should lilypond extract and build makeinfo as part of its own
build process, or should a new port be created for makeinfo?
