Hi, 

first of all, you are doing tooo many wrong, completely wrong, things:

> env TEXINPUTS="./:EXINPUTS" latex   sigproc-sp-copy.tex

Wrong wrong wrong wrong.

Setting TEXINPUTS overrides *all* default settings. That mean, you
tell TeX to *ONLY* search in
	./
	EXINPUTS
???

Of course you get:
> This produced "LaTeX Error: File `epsfig.sty' not found".

No surprisingly, why should there be an epsfig.sty there.


> :  #env TEXINPUTS="./:EXINPUTS" latex  sigproc-sp-copy.tex
> env TEXINPUTS="./:EXINPUTS" latex   sigproc-sp-copy.tex

Furthermore, since this is a *make* file, you probably have in your
makefile
	env TEXINPUTS=./:$TEXINPUTS latex ...
which is wrong, since make expands $T to nothing, which leaves
you with
	./:EXINPUTS
which is rubbish....

> インストール・削除・更新されるパッケージがありません。

それをわかりますよ。関係ない。

> :  #env TEXINPUTS="./:EXINPUTS" latex  sigproc-sp-copy.tex
> env TEXMF=".:EXMF:/usr/share/texlive/texmf-dist/tex/latex/"

Same error here:
	TEXMF=".:$TEXMF" ...
in Makefile, $T expanded to nothing

You sould *NOT* need to chagne $TEXMF (or in Makefile you are supposed
to write $$TEXMF, btw)


> tcfmgr: config file `tcfmgr.map' (usually in $TEXMFMAIN/texconfig) not

Of course, because you redefined $TEXMF to a rubbish value, that
cannot work ...

>    <==== Note the next line. Somehow epsfig.sty suddenly was found and

You probably have other environment variables set that breaks 
everything.

Can you send the output of
	tlmgr conf



===============================

Fixing your problem:

You have to *correctly* redefine TEXINPUTS. But you have to say what
you want to achieve.

*** IMPORTANT *****
Never forget a *TRAILING*COLON* in TEXINPUTS.
*******************

What you can do:
	TEXINPUTS=./:/home/foobar/bla//:
Note:
* trailing : searches for the *default* setting in texmf.cnf, too
  *NEVER* remove that
* ./ is *anyway searched, no need.
* If you want to search *arbitrary* below ., then you have to use double /:
	.//
 (but be warned, that can be expensive. Think about doing this in 
  the root of your installation, in this case *ALL* of your harddisk will
  be searched!!!)


Then, FIX YOUR MAKEFILE
========================
If you *REALLY* need to change TEXINPUTS (which I *strongly* doubt!)
you need to do the following:
	target:
		env TEXINPUTS=/some/dir/: latex ....
and if you need to expand a *shell* variable, you need to use $$FOO


============================

End of the line:
* learn to write Makefiles
* don't play around with settings, it works as is
* send me your tlmgr conf


Finally, concerning your *suggestion*
> In any case, after this experience, I think the installers of

Thanks, I make a lot of tests before uploading packages.

The problem is that *you* messed up your environment. That is nothing
a package maintainer can prohibit. There are valid use cases for
setting TEXINPUT and TEXMF, but in your case *all* of them were *invalid*.
