Here is what to do:
Check ../config.h and see whether HAVE_LONG_DOUBLE is defined, you should be able to locate a line saying:

#define HAVE_LONG_DOUBLE 1

If you can't find such a line your system doesn't support long double IEEE precision.
Edit the files kcalctype.h, configdlg.cpp, kcalc.cpp and kcalc_core.cpp and remove the lines:

#ifdef HAVE_LONG_DOUBLE
#undef HAVE_LONG_DOUBLE
#endif
