Thanks for the correction.
Here I plead guilty. I was confused, when reading kpathsea.pdf, about
the options --progname and --engine. Earlier in this thread I tried
the latter, but the results felt a bit odd (no different search paths
for latex and xelatex, and this strange kpsewhich subdirectory I
never heard about earlier):

Now with --progname the results make more sense. Taking TeXLive-2007
for example (with output reformatted for clarity):
$ texdist --texdist=TeXLive-2007 "kpsewhich --progname=latex --show-
path=tex"
.

Thus it seems that, in TeXLive-2007, when XeLaTeX is run:
- The directories searched are, by decreasing order of precedence:
current directory
tex/xelatex/
tex/latex/
tex/generic/
tex/
- For each directory the texmf trees searched are, by decreasing
order of precedence:
~/.texlive2007/texmf-config/
~/.texlive2007/texmf-var/
~/Library/texmf/
/usr/local/texlive/2007/texmf-config/
/usr/local/texlive/2007/texmf-var/
/usr/local/texlive/2007/texmf/
/usr/local/texlive/2007/../texmf-local/
/usr/local/texlive/2007/texmf-dist/
When LaTeX is run things are identical, *except* that the tex/
xelatex/ directory is not searched.
In gwTeX things are a bit different. gwTeX seems more compatible with
older setups, as it allows for the existence of a xetex/ directory
alongside the tex/ directory. For XeLaTeX:
- The directories searched are, by decreasing order of precedence:
current directory
xetex/xelatex/
tex/xelatex/
xetex/latex/
tex/latex/
xetex/generic/
tex/generic/
xetex/
tex/
- For each directory the texmf trees searched are, by decreasing
order of precedence:
~/Library/texmf/
/usr/local/gwTeX/texmf.local/
/usr/local/gwTeX/texmf.pkgs/
/usr/local/gwTeX/texmf.gwtex/
/usr/local/gwTeX/texmf.texlive/
/usr/local/gwTeX/texmf/tex/
For LaTeX things are identical, *except* that the tex/xelatex/ and
xetex/ directories are not searched.
That said, I'm still not at ease with the search order of the texmf
trees in TeXLive-2007, which feels overly complicated. In particular,
one thing seems error-prone:
- On one hand /usr/local/texlive/2007/texmf-config/ and /usr/local/
texlive/2007/texmf/ are searched *after* ~/.texlive2007/texmf-config/
and ~/Library/texmf/, but *before* /usr/local/texlive/texmf-local/.
- On the other hand /usr/local/texlive/2007/texmf-config/ and /usr/
local/texlive/2007/texmf/ do contain important configuration files,
that the user might decide to modify to set up her needs:
/usr/local/texlive/2007/texmf-config/tex/generic/config/
pdftexconfig.tex
/usr/local/texlive/2007/texmf/tex/latex/config/color.cfg
/usr/local/texlive/2007/texmf/tex/latex/config/graphics.cfg
/usr/local/texlive/2007/texmf/tex/latex/config/hyperref.cfg
Thus the above seems to mean the user must put updated configuration
files inside ~/.texlive2007/texmf-config/ or ~/Library/texmf/, but
*not* inside /usr/local/texlive/texmf-local/, for them to be taken
into account in all cases.
This seems wrong in two respects:
- System-wide local customizations put inside /usr/local/texlive/
texmf-local/ are supposed to be taken into account, unless a user
decides to supersede them explicitly by putting stuff inside
~/.texlive2007/texmf-config/ or ~/Library/texmf/.
- The above seems to make it impossible to set up system-wide local
customizations, given /usr/local/texlive/texmf-local/ cannot be used
safely for them.
I hope I misunderstood something.
