Since MacTeX 2017 is released, I updated it to the latest version. However, something wrong happened with dvipdfmx and xdvipdfmx in Emacs while similar procedure is ok under bash shell. Let me explain it with some LaTeX codes:

Trying here with your sam2.tex and a rose.eps file, everything works fine with XeLaTeX on TeXShop.
The problem seems to happen when Emacs asks dvipdfmx to process the generated DVI file in the first example, and the (invisibly) generated XDV file in the second example, yielding each time
> Unable to read environment locale:exit now.
On StackExchange, at
one answer says
> You should update AUCTeX to the latest ELPA version available, 11.90.2, it has a fix for TeX Live 2017.
the same user (giordano) provides more detail
> AUCTeX parses the output buffer in order to report errors and warnings, and if there is none of them, it looks for a line like

> However, since April 2017, the date format of LaTeX has been changed from yyyy/mm/ddto yyyy-mm-dd and your version of AUCTeX can't find the line
> LaTeX2e <2017-04-15>
> This has been already fixed upstream, you only need to update your AUCTeX package. The fix is present in the latest ELPA version (11.90.2), which is by far the best and simplest way to install (and then update) the package.
Could this be connected?
