First of all: I would personally not bother too much about installing
them to the proper place. Every TeX installation differs. I just
replied since I saw the comment (I never use "make install" for
gnuplot, I just manually copy the binary and maybe prologues.ps if I
happen to need it.)
You may try to execute
(or locate texmf.cnf; they are read one after another in some
particular well-defined order that I don't know by heart).
I have one at
and one at
that defines the variable as
TEXMFLOCAL = $SELFAUTOPARENT/../texmf-local
It's not environmental variable as it would spoil the environment too
much, though environmental variables do take precedence if you set
work on your machine?

It's not environmental variable, it's hidden in texmf.cnf that
kpsewhich/kpsexpand should know about, but my answer would be just:
"Nothing". If anyone wants to use it, he should be able to put the
file anywhere (even in local folder).

I can try to answer any TeX-related question, send some short scripts
that do simple tasks (or talk in pseudocode) ... as long as this
doesn't mean that I need to touch Makefiles and configure.in.
In the particular example above the only thing that I'm not absolutely
sure is how shell expansion works. The following definitely doesn't
work for me:
does and returns
but this will be different on every single distribution. Performing
"sed" based on existence of "share" is pointless. Taking TEXMFLOCAL is
a wiser choice, but it may have the same form as the expression above
(not likely, but allowed). I would imagine that this should work even
in any TeX Live or even in tetex.
