Thanks, applied to the maint branch.  I added (in the previous commit)
a fairly simple fix to the build system to make sure that we use the
system-provided header files for blkid or uuid if we are using the
system-provided blkid or uuid libraries.  I've tested most of the
combinations except for with the latest bleeding edge blkidv2
libraries --- can you double check to make it works in that case.
