A generic answer that may or not apply to this specific case:

As the error message hint at, aclocal-1.15 should only be required if you modified files that were used to generate aclocal.m4

If you don't modify any of those files (including configure.ac) then you should not need to have aclocal-1.15.

In my case, the problem was not that any of those files was modified but somehow the timestamp on configure.ac was 6 minutes later compared to aclocal.m4.

I haven't figured out why, but a clean clone of my git repo solved the issue for me. Maybe something linked to git and how it created files in the first place.

Rather than rerunning autoconf and friends, I would just try to get a clean clone and try again.

It's also possible that somebody committed a change to configure.ac but didn't regenerate the aclocal.m4, in which case you indeed have to rerun automake and friends.
