I usually install in more nonstandard locations - ones I can write to.
So no sudo is required.

What's the problem?  you could just change the owner of the files to
yourself while you are root.
Or afterwards, you can delete them, as long as you can write to the
directory they reside in.
find builddir -user root
should find them all.
Then you can use  command substitution, xargs, or just find itself,
to chown / rm these files.
