I've been trying to install the TeX minimals on a new Mac. While MK II works, not so MK IV.

I get the error message MTXrun | unknown script 'context.lua' or 'mtx-context.lua'

Here is what I did:

Downloaded TeXLive 2010 

Then followed the instructions at

I did this a few years back without a hitch, so I am wondering what is different now.

In any case, in the above instructions, under Configuring ConTeXt, instep 4, 

the copies file has already the indicated changes in it.

I used the same paths as indicated and ran luatools --generate as well as context --make

Everything went ok without error messages. I then configured TeXShop as explained.

As I said, MKII works  fine but MKIV gives the error message.

I searched the wiki for it and there seem to be some related reports, but I couldn't find a resolution.

Any suggestions? If all fails I'll try to clone an older installation.
