I have placed updated package descriptions for qrupdate, arpack, and octave in my experimental: http://fink.cvs.sourceforge.net/viewvc/fink/experimental/alexkhansen/common/finkinfo/sci/ The non-atlas variants use -ff2c, and the atlas variants don't. Octave-3.0.5 is included in these updates, even though it doesn't use qrupdate or arpack. - -- Alexander Hansen, Ph.D. Fink User Liaison http://finkakh.wordpress.com/ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk5z36sACgkQB8UpO3rKjQ+d3ACfQ4m8eSL/4tqJJpdhG6q0A2hI evkAnR7p3scm7V3c2/Z9NZ+42xIdVi98 =eaje -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ BlackBerry® DevCon Americas, Oct. 18-20, San Francisco, CA http://p.sf.net/sfu/rim-devcon-copy2 _______________________________________________ Fink-users mailing list Fink-users@lists.sourceforge.net List archive: http://news.gmane.org/gmane.os.macosx.fink.user Subscription management: https://lists.sourceforge.net/lists/listinfo/fink-users
