[Rd] Rd2pdf and Rd2dvi don't find texi2dvi

[Tobias Erhardt]

Okay, i did compare  the versions of texi2dvi within R and the shell, they are both the same. 

Regarding the environmental variabels, this is what printenv gave me:

TERM_PROGRAM=iTerm.app
TERM=xterm
SHELL=/bin/bash
TMPDIR=/var/folders/3B/3BhLCRj+FISLJAbkj65bUU+++TI/-Tmp-/
Apple_PubSub_Socket_Render=/tmp/launch-N5Bzur/Render
COMMAND_MODE=unix2003
SSH_AUTH_SOCK=/tmp/launch-p1c1Db/Listeners
__CF_USER_TEXT_ENCODING=0x1F5:0:3
PATH=/Library/Frameworks/Python.framework/Versions/2.6/bin:/Library/Frameworks/Python.framework/Versions/2.7/bin:/Applications/Octave.app/Contents/Resources/bin/:/Applications/GMT//bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/opt/local/bin:/usr/local/git/bin
PWD=/usr/bin
EDITOR=mate -w
NETCDFHOME=/usr/local/
LANG=de_DE.UTF-8
SHLVL=1
COLORFGBG=0;15
LC_CTYPE=en_US.UTF-8
DISPLAY=/tmp/launch-VKiS22/org.x:0
_=/usr/bin/printenv

and this is what Sys.getenv(c("PATH", "TEX")) gave me:

PATH 
"/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/opt/local/bin:/usr/local/git/bin:/usr/local/bin" 
TEX 
"" 

I dont't really know my way around system variables but i hope that this helps.

I'm open for any suggestions
