If you happened to upgrade -current in a certain window, "make delete-old-libs" would remove the necessary libraries, even though "make delete-old" didn't know that it should delete /usr/bin/f77, so the lapack build would bail out because f77 couldn't find libg2c. Setting FC=gfortran42 is is sufficient to get lapack and math/atlas-devel to build, assuming that lang/gcc42 is installed. BTW, math/atlas* has been using the combination of gcc34 and gfortran42 on -current for a while now, which means that it requires the installation of two different gcc ports ...Received on Mon Jun 04 2007 - 18:30:18 UTC
