XeTeX and xdvipdfmx problem in Texstudio (2)

Question

I'm issuing the same problem like in this question, but unfortunately it was closed for whatever reason: XeTeX and xdvipdfmx problem in Texstudio

When I try to compile the .tex file from the commandline it works with no errors, it seems that Texstudio doesn't use the same PATH variable as my shell does.

I can reproduce this error by removing the TeX folder from my PATH variable and execute:

simon$ /usr/texbin/xelatex table.tex 
This is XeTeX, Version 3.1415926-2.5-0.9999.3 (TeX Live 2013)
 restricted \write18 enabled.
entering extended mode
(./table.tex
LaTeX2e <2011/06/27>

======= some latex processing stuff ======= 

Overfull \hbox (15.0pt too wide) in paragraph at lines 39--40
[][] 
[1] (./table.aux) )
sh: xdvipdfmx: command not found
(see the transcript file for additional information)
Error 32512 (driver return code) generating output;
file table.pdf may not be valid.

I think that Xelatex causes this error by calling xdvipdfmx instead of ./xdvipdfmx internally, because other TeX Tools work fine, even without PATH variable set.

Version of Xelatex is:

simon$ /usr/texbin/xelatex -v

The Mac version of TeXstudio automatically adds a directory to the PATH, but it's set to /usr/local/texlive/2012/bin/x86_64-darwin/ by default. If you click Show Advanced Options in the Preferences page, under Build > Build Options > Additional Search Paths, change Commands ($PATH) to /usr/texbin and it should work, even if you upgrade MacTeX or TeX Live.

Edit: In Mac OS 10.11 El Capitan, users can't put anything in /usr/ anymore so MacTeX symlinks to /Library/TeX/texbin instead.
