What I've done for now is to create a tgz of the 3 *.f files above, and put it at http://eis.bris.ac.uk/~mexas/blasmach.tgz I then put in the Makefile MASTER_SITES= http://netlib.org/slatec/ \ http://eis.bris.ac.uk/~mexas/ DISTNAME= ${PORTNAME}_src blasmach This seems to work, but it relies on blasmach.tgz being untarred *after* slatec_src.tgz. I guess this is an unsafe assumption? many thanks anton -- Anton Shterenlikht Room 2.6, Queen's Building Mech Eng Dept Bristol University University Walk, Bristol BS8 1TR, UK Tel: +44 (0)117 331 5944 Fax: +44 (0)117 929 4423 _______________________________________________ freebsd-ports@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ports To unsubscribe, send any mail to "freebsd-ports-unsubscr...@freebsd.org"
