Hello,
I confirm the command realpath wasn't installed by default on my
debian either. And it seems it can be easily replaced by readlink -f.
And actually I find its use doubtful.

However, as you may have seen, these scripts are quite new and may
have bugs. Using pushd/popd in a /bin/sh script is a bug. IIRC, by
default, on debian, /bin/sh points to dash, and not bash.

About the make spotless, I don't know much about the Makefiles, thus I
can't help, sorry.

I hope Matt will see this mail. :)
