Hi Thomas and Steve, Thanks for your clarification. I rewrote this port completely and update to 3.1.1. Now at least dlamch/slamch are build with -O0. Hope now it works well. I haven't tried yet with g77 and may not work with it. % cd /usr/ports/math/lapack % rm -rf work ; make > & log & % grep slamch.f log gfortran42 -O0 -c slamch.f -o slamch.o gfortran42 -O0 -fpic -c slamch.f -o slamch.o gfortran42 -O0 -pg -c slamch.f -o slamch.o From: "Thomas D.
