Comment:

 With ngspice @26_0 on Yosemite, I get the exact same error when trying to
 plot anything:

 {{{
 Circuit: *rc filter ac example

 ngspice 2 -> run
 Doing analysis at TEMP = 27.000000 and TNOM = 27.000000

 Warning: v1: has no value, DC 0 assumed


 No. of Data Rows : 701
 ngspice 2 -> plot db(v(out))
 Can't open viewport for graphics.
 }}}

 I have not many ports installed now as I have just upgraded to Yosemite
 from Mountain Lion and chose to start with a clean MacPorts installation.
 However, the very same error occured before, on Mountain Lion, too. XCode
 and XQuartz 2.7.7 are both installed and up to date. The circuit loaded to
 test this was the first example netlist from http://www.ngspice.com (The
 simple RC filter that's in the text area).

 There were no build errors when I installed ngspice.

 If you need more information to debug just ask, I will try to gather them
 for you.
