* /var/tmp/portage/sci-chemistry/ball-1.4.2/work/BALL-1.4.2/source/MOLMEC/MINIMIZATION/shiftedLVMM.C:769:46:   required from here
* /var/tmp/portage/sci-chemistry/ball-1.4.2/work/BALL-1.4.2/include/BALL/MATHS/common.h:175:18: error: ‘isnan’ was not declared in this scope, and no declarations were found by argument-dependent lookup at the point of instantiation [-fpermissive]
