A ticket was already filed for this MacPorts bug a month ago: "pstoedit 3.70 does not have most of the available drivers that 3.62 did" http://https://trac.macports.org/ticket/47354 One of the missing drivers is the "pic" driver.
I'm finding that pstoedit doesn't appear to support the "pic" format on my OS X 10.10 Yosemite Mac. I'd like to think this is some install or configuration error, as it's just like the other errors other posters have presented here.
The error when running gerber2graphtec.py is (last line): IOError: [Errno 2] No such file or directory: '_tmp_gerber.pic'
And, sure enough, no pic file was created. The pdf file was created, but no pic file can be exported from the pdf via pstoedit:
Unsupported output format pic Available formats : psf:.fps:Flattened PostScript (no curves) (built-in) ------------------------------------------- ps:.spsc:Simplified PostScript with curves (built-in) ------------------------------------------- debug:.dbg:for test purposes (built-in) ------------------------------------------- dump:.dbg:for test purposes (same as debug) (built-in) ------------------------------------------- gs:.gs:any device that Ghostscript provides - use gs:format, e.g. gs:pdfwrite (built-in) ------------------------------------------- ps2ai:.ai:Adobe Illustrator via ps2ai.ps of Ghostscript (built-in) -------------------------------------------
I'm still investigating, but beginning to wonder if the script will need to be rewritten for a format other than pic. MAJ
