In principle you need to contact the upstream developer (unless it's
Aditya reading the mailing list and pointing you to the patch :)

 This will be fixed in the next release of pgfplots.

t-tikz in distribution uses the master from git repository on
sourceforge (even though I'm not exactly sure how frequently it
updates). In any case, looking at the current state, I see the lua
file is already inside tex, not inside scripts, so Aditya's
comment to wait for the released patch should no longer hold. If the
problem persists, it might be a different bug (I didn't test
anything).

I reproduced it with a brand new clone of minimals.
The fix for the last bug is indeed already there.

You can test it with the following MWE:

  \usemodule [pgfplots]

  \starttext
\starttikzpicture
  \startaxis
\addplot coordinates {
  (0, 0)
};
  \stopaxis
\stoptikzpicture
  \stoptext

If this is indeed a bug in pgfplots and not my setup I'll report it
upstream.

(My system is an up-to-date Archlinux 64bit)

Regards,
Thomas

I can reproduce the problem on my machine and the patch solves the
problem, but something seems really weird. Why on earth does it want
to load files from /usr/local/lib/lua/5.1 and why does it want to load
a binary module instead of a lua file? (I don't have that folder, but
even if I had it, pgfplots wouldn't be there)

So can I.


but something seems really weird. Why on earth does it want

and why does it want to load
a binary module instead of a lua file?


http://www.luafaq.org/#T1.19



(I don't have that folder, but
even if I had it, pgfplots wouldn't be there)


  \startluacode
print(package.cpath)
  \stopluacode

gives

./?.so;/usr/local/lib/lua/5.1/?.so;/usr/local/lib/lua/5.1/loadall.so

so

require('pdfplots.lua')

searches for the library file in those folders.


! LuaTeX error \directlua :1: module 'pgfplots.lua' not found:
no field package.preload['pgfplots.lua']

I think that pdfplots should be using dofile rather than require.

This will be fixed in the next release of pgfplots.

Hm,

it seems like my general purpose search engine missed an existing report
about the same issue, for which Aditya provided a fix.
(http://www.mail-archive.com/ntg-context@ntg.nl/msg66002.html)

So there are now two fixes.
Sorry for the noise if mine is nonsense :-)
