[texhax] trouble installing TeX Collection 2013

[Thomas Schneider]

I got the DVD for TeX Collection 2013 today and started installing it
on my Mac OS X 10.6.8 system.

It seems much more complex than previous installations, with three
unequal parts!  This is confusing.

I accidently did that A4 part and so had to start over again.
I did this by moving the /usr/local/texlive/2013
directory to /tmp.

I found that latex was no longer in my path and so I followed:

 Most importantly, add /usr/local/texlive/2013/bin/x86_64-darwin
 to your PATH for current and future sessions.

This was not required previously.  It's not a good idea to have to change
the path every year!

I still don't find latex in my path.

I discovered that the /usr/local/texlive/2013 directory was not permitted
to be readable by everyone as it had in prevous years:

toot 8% cd texlive/
toot 9% ls
2009/        2010/        2011/        2012/        2013/        texmf-local/
toot 10% dir
total 0
drwxr-xr-x   8 root  wheel  272 Jul  9 17:12 ./
drwxr-xr-x  11 root  wheel  374 Sep  4  2011 ../
drwxr-xr-x  21 root  wheel  714 Nov  7  2009 2009/
drwxr-xr-x  24 root  wheel  816 Mar  5  2011 2010/
drwxr-xr-x  23 root  wheel  782 Sep 20  2011 2011/
drwxr-xr-x  23 root  wheel  782 Aug 23  2012 2012/
drwx------  20 root  wheel  680 Jul  9 17:42 2013/
drwxr-xr-x   9 root  wheel  306 Jan 19  2010 texmf-local/

I fixed that and still got no latex, other things were not permitted.

So I did a recursive permission to the entire directory:

sudo chmod -R a+rX 2013

NOW I have a latex!!!

I'm glad to report that it works and I got my test document.

The log file begins:

This is pdfTeX, Version 3.1415926-2.5-1.40.14 (TeX Live 2013) (format=latex 2013.7.9)  9 JUL 2013 19:54
entering extended mode

So the general solution appears to be that people must do this:

cd /usr/local/texlive
sudo chmod -R a+rX 2013

This might be required for everyone on Unix systems ...
