This appears to be one of those unfortunate errors that sometimes occur when the presence of additional software on your system adversely affects a build, in a way that isn't seen on the test machines or the package-building cluster, because those machines start builds in a clean sandbox, with only certain pre-computed dependencies installed. Here galculator's faulty configure script (which was probably written and tested on a system that has a recent version of gcc as the default compiler) looks for and finds libquadmath, which is part of gcc-4.[678], and then attempts to use it, without checking if the compiler that you are using can use GCC quadmath: > checking for sinhq in -lquadmath... yes You can either patch the port's sources, or add CONFIGURE_ENV+= ac_cv_lib_quadmath_sinhq=no to an included Makefile, or (if you need the extended precision features) try to build the port with USE_GCC=4.6+. b.
