I would guess that /var/lib/texmf/ is explicitly added in the gentoo
builds of teTeX. I find it difficult to imagine how the web2c configure
scripts could pickup this variable all by itself.

On Debian, /usr/share/texmf/web2c/texmf.cnf is a symlink to the
/etc/texmf/texmf.cnf. In addition, Debian uses a shared libkpathsea such
that tex at all don't know about such compiletime defaults. I haven't
tried building XeTeX that way, though, and I don't know if that is also
done on Gentoo.

Maybe because you are searching for 'hyphen.tex', which is probably
below /usr/share/texmf. I think XeTeX needs compiletime defaults only
for finding texmf.cnf. After that, the paths defined in there should be
used. So it might make sense to use 'kpsewhich texmf.cnf' instead. But
maybe the setup used by Gentoo with texmf.cnf in /var/lib/texmf is
simply broken?
