[tex-live] Missing "ppc" symbolic link in .FactoryDefaults/gwTeX-2003-2005 ?

[Richard Koch]

Jean-Francois,

Thanks for the detailed bug report!

When MacTeX installs TeX Live, it creates TeX Distribution structures for itself, and for three
other distributions: Fink, MacPorts, and Gerben's original teTeX (but not gwTeX). That's because
these three distributions don't create their own TeX Distribution structures. But MacTeX does not
edit TeX Distribution structures created by other distributors.

Thus the gwTeX structure contains a powerpc link but no ppc link because that's what Gerben
originally provided. This wasn't a mistake on his part; the ppc link came later.

The puzzling feature of your bug report is that your /usr/texbin points to 

	../Library/TeX/Distributions/.DefaultTeX/Contents/Programs/ppc

I have now checked the install scripts for MacTeX 2010, 2009, and 2008 and BasicTeX and all
create a link to 

	../Library/TeX/Distributions/.DefaultTeX/Contents/Programs/powerpc

I also checked my own powerpc machine, which has this second link. The actual code which
does this is in a postflight script. The script first removes any existing symbolic link named
/usr/texbin, and then does the following:

	PROCESSOR=`/usr/bin/uname -p`

	if [[ "$PROCESSOR" == "powerpc" ]]; then
	echo "### setting program link powerpc"
	ln -fhs ../Library/TeX/Distributions/.DefaultTeX/Contents/Programs/powerpc /usr/texbin

Thus the real puzzle is why your /usr/texbin link is incorrect. 

I have never heard of

	/usr/powerpctexbin

and have no idea where that came from.
