Dear ntg-context@ntg.nl:

I am new to ConTeXt, so if this is not a very good question, please accept my apologies in advance.  I first tried sending this message to the help address at contextgarden.net, and the reply I received suggested that this list would be the more appropriate venue.

I am trying to install ConTeXt on my Mac, and am following the StandAlone ConTeXt instructions on the page:

http://wiki.contextgarden.net/Mac_Installation#Installing_MacTeX

I installed MacTeX without problem, and then tried to follow the instructions for Standalone ConTeXt.  At the end of Section 3.2 on that page, when I tried to execute the command:

sh ./first-setup.sh --modules=all --engine=luatex

it ran for a minute or so, but ultimately gave me the error message copied below.

This is LuaTeX, Version beta-0.85.0 (TeX Live 2016/dev) (rev 5550)  (INITEX)
 system commands enabled.
(/sw/share/texmf-dist/tex/context/base/cont-en.mkiv (/sw/share/texmf-dist/tex/context/base/context.mkiv (/sw/share/texmf-dist/tex/context/base/syst-ini.mkiv
! Undefined control sequence.
l.842     \pdfminorversion

It seems that I am missing some kind of software prerequisite, but I am really not sure.  Any suggestions you might have for getting around this problem would be very much appreciated.

Sincerely,
Bruce Boghosian
