Ralf,

I think what Gaby is suggesting is that aaa.tex would be extracted
to some directory other than the current directory, e.g.

  $ noweave axiom.sty.pamphlet > intermediate/axiom.sty.tex

then presumably calling

  $ tex intermediate/axiom.sty.tex

even though it contains

  \usepackage{axiom.sty)

will not look for axiom.sty in the intermediate directory -
only the current directory.

Your test did not test this case.

Try this:

$ mkdir intermediate

Create the file 'intermediate/axiom.sty.tex'

%%%BEGIN intermediate/axiom.sty.tex
\documentclass{book}
\usepackage{axiom}
\begin{document}
test
\end{document}
%%%END intermediate/axiom.sty.tex

Now create 'axiom.sty.tex' file in the current directory

%%%BEGIN axiom.sty.tex
\message{======= I am axiom.sty.tex =======}
%%%END axiom.sty.tex

Plus two 'axiom.sty' files - one in the current directory

%%%BEGIN axiom.sty
\message{======= I am just axiom.sty =======}
%%%END axiom.sty

and one in the intermediate directory

%%%BEGIN intermediate/axiom.sty
\message{======= I am intermediate/axiom.sty =======}
%%%END intermediate/axiom.sty

Remember also that we still have the axiom.sty file in the share
texmf directory tree and tex appropriately initialized to look
for it there. That makes three 'axiom.sty' files in all.

--------

Now from the current directory run

$ latex intermediate/axiom.sty.tex

---------

So indeed, \usepackage{axiom} does cause latex to look in the
*current* directory for 'axiom.sty.tex'.

What happens if we rename 'axiom.sty.tex' and try again?

$ mv axiom.sty.tex axiom.sty.tex_old

$ latex intermediate/axiom.sty.tex
This is pdfeTeX, Version 3.141592-1.21a-2.2 (Web2C 7.5.4)

Now the devil finds 'axiom.sty' in the current directory!

Finally, let's rename 'axiom.sty' and try a 3rd time.

$ mv axiom.sty axiom.sty_old

$ latex intermediate/axiom.sty.tex
This is pdfeTeX, Version 3.141592-1.21a-2.2 (Web2C 7.5.4)

---------

Finally success. latex finds the copy of axiom.sty where it is
supposed to - in the share texmf tree (no messages).

Summary: One way to solve this stupid problem is to extract the
.tex file to an intermediate directory different from the current
directory when we run latex.
