That is one place where you have not followed the BLFS instructions :
probably harmless, but it's not how we do it.  If you look at our
instructions, we use $TEXARCH.  The reason for that is because we
originally used the binaries to bootstrap building from source, and
doing that ensures the from-source programs overwrite the pre-built
ones.

I asked about the PATH because I wondered if kpsewhich was a remnant
of an older install, but apparently it is not.

Maybe.  You can try that change out for yourself and see if it fixes
it.  Unless we (BLFS) say that an instruction is optional (e.g.
building API docs for some programs, or explanations of optional
configure switches), we expect you to use all the instructions we
offer.

If you look at the libraries listed at the bottom of that page, ALL
of them are in /opt/texlive/2015/lib : I am surprised that kpathsea
runs at all if it cannot find its libraries, and similarly I would
expect problems with the lua parts of TeX.

But please answer Norbert's questions first, he is more likely to
get to the root of the problem (and that may still be in what we are
doing ;)
