My suggestion is as follows: (I've not tested yet.) PORTNAME=3D slatec MASTER_SITES=3D http://netlib.org/slatec/ \ http://netlib.org/blas/:mach DISTFILES=3D ${PORTNAME}_src.tgz \ d1mach.f:mach i1mach.f:mach r1mach.f:mach EXTRACT_ONLY=3D ${PORTNAME}_src.tgz Then you could copy these three files from DISTDIR to the work directory. post-extract: @cd ${DISTDIR}/ && ${CP} d1mach.f i1mach.f r1mach.f ${WRKSRC}/src/ Hope that helps.
