What do you mean by "pdf is not present but pdfcairo is present"?
If either of pdflib or pdfcairo libraries are compiled with gnuplot, 
then in both cases
	set term pdf
sets the output to pdf. There is no "different" command. The command
	set term
shows that there is "pdfcairo" terminal which is the full name of the new
pdf terminal, i.e.
	set term pdfcairo
can be used as well.

So, how does Octave know/detect whether gnuplot has/has not pdf (any) 
terminal?
