The .so are only used when linking, and not the ones used at runtime generally (the full version, e.g. .so.1.2.3 is). Which version exactly depends on your installation, but I actually advise you against doing those softlink. You should instead specificaly link the GOTO library to numpy, by customizing the site.cfg, cheers, David _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
