I prefer adding
#define PACKAGE_VERSION "34+"
to sharedspice.h.

sharespice.h has been and will always be there.
In old ngspice releases PACKAGE_VERSION is not defined. But config.h is 
there, containing its PACKAGE_VERSION. In ngspice-34 unfortunately 
PACKAGE_VERSION will not be available. But the code snipped below
starting at line 161 in  common/build_version.cpp (not tested) should 
just return "unknown". No user interaction is required. In ngspice-35
PACKAGE_VERSION will be available in sharedspice.h.

#else
    #include <ngspice/sharedspice.h.h>
    #ifdef PACKAGE_VERSION
        aMsg << indent4 << "ngspice: " << PACKAGE_VERSION << eol;
    #else
        aMsg << indent4 << "ngspice: " << "unknown" << eol;
    #endif
#endif

The disadvantage of the compile time approach of course is that it would 
not follow a user who just upgrades (or downgrades?) ngspice.
