Hello Joost,

Yes, I see them too, but they are pointing to the more recent 2012
release of texlive, not the older 2011 one. What I don't understand is
where /sudo/ finds the environment when called without the "-i" option
(and in particular, that entry for texlive 2011). The manpage seems to
say that it simply uses the current environment (quoting the manpage :
"Note, however, that the actual PATH environment variable is not
modified and is passed unchanged to the program that sudo executes.")
but that does not seem right.
