[OS X TeX] [MacTeX 2015] Cannot open Ghostscript for piped input

[Se Fer]

Hello all

hope I can find some help here. I have an (now again) fresh installation of
MacTeX 2015 running on OS X Yosmite. I haven't installed any other version
of ghostscript but the MacTeX-package.

I removed everything on my drive today to start fresh because I am not able
to fix the following error:

"Error: Cannot open Ghostscript for piped input"

Complete error as an example:

"epstopdf ($Id: epstopdf.pl 36129 2015-01-24 00:30:11Z karl $) 2.23 !!!
Error: Cannot open Ghostscript for piped input: gs -q -dSAFER -dNOPAUSE
-dBATCH -sDEVICE=pdfwrite
-sOutputFile=pic/webrtc-triangle-eps-converted-to.pdf
-dPDFSETTINGS#/prepress -dMaxSubsetPct=100 -dSubsetFonts=true
-dEmbedAllFonts=true -dAutoRotatePages#/None - -c quit"

Both texpad and TeXstudio can't find a valid ghostscript installation and
their fields are blank. I tried adding the following command to the
Ghostscript-field within TeXstudio  ' "/usr/local/bin/gs "?am.ps" ' but it
doesn't fix the error.

Running "which gs" in terminal gives no output. But running "sudo which gs"
I get the following output: "/usr/local/bin/gs" ...
It looks like everything is in place according to the file structure given
from the package-file.

Yours faithfully
Sefer
