GNAT (GNU Ada Translator) 2005 and 2012 require LAPACK and BLAS libraries to implement certain numeric functionality. I'm not sure where in the gcc series this entered but I think it was 4.3. In the Ada Reference Manual this functionality is described in Annex G.3. You might have both C and Fortran versions of these libraries--OS X does. Ada can handle either (in principle) and I don't think it matters which one is used. I don't know which is currently being linked on OS X without looking into it. (Actually, I think OS X puts them both into the same framework which could mean in the same library.) There is a build flag in PLplot to indicate the presence or absence of Ada 2005 (versus Ada 95) but we should probably move towards using it when possible as this compiler becomes more widespread. In PLplot, there is minimal usage of this functionality--only some type declarations for arrays of floating point numbers. If the flag for Ada 2005 is not set, cmake causes these declarations to be made in the bindings themselves. So if you don't want to link the libraries, you should be able to proceed with PLplot by adjusting the flag. Note that pretty much everywhere in PLplot including bindings and docs, "Ada 2007" is used instead of "Ada 2005" which is my fault. (The Ada 2005 spec was not finalized until early 2007.) I wonder if a global change is possible without wrecking something.
