Trying this here in Terminal:

$ bash -c 'echo $PATH'
/Users/brunovoisin/Library/TeX/LocalTeX/texbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/usr/texbin

which points to a significant change: /usr/local/bin comes now first in the default path.

Checking with Time Machine backups, it seems that Yosemite Public Beta 2 (installed here on September 6) changed the content of /etc/paths, from 

/usr/bin
/bin
/usr/sbin
/sbin
/usr/local/bin

to

/usr/local/bin
/usr/bin
/bin
/usr/sbin
/sbin

I have no idea why. Probably will have consequences for Homebrew users. Because of the potential implications for MacTeX’s Ghostscript (hopefully none), I’m cc’ing the MacTeX list.
