Hi Bruce, I downloaded the 060 version of the source code tarball from your website, and followed the instructions to become root, unzip the file and the following happened: stefano# cd horae-060 stefano# perl Makefile.PL === The Ifeffit wrapper, Athena, Artemis, and Hephaestus === This is Mac OSX. Checking dependencies ... Dependencies ok. Cool! Reading configuration file: Ifeffit/lib/athena/athena.config Wrote Ifeffit/lib/athena/athenarc Ifeffit/lib/athena/athenarcw Ifeffit/lib/athena/athena.ini athena_parts/rc.pl Reading configuration file: Ifeffit/lib/artemis/artemis.config Wrote Ifeffit/lib/artemis/artemisrc Ifeffit/lib/artemis/artemisrcw Ifeffit/lib/artemis/artemis.ini artemis_parts/rc.pl Assembled athena.pl from its parts (athena_parts/).

I am using a Powerbook G4 with OS X Tiger (10.4.4) Cheers, Stefano -- ____________________________________________ Stefano Ciurli Professor of Chemistry Laboratory of Bioinorganic Chemistry Department of Agro-Environmental Science and Technology University of Bologna Viale Giuseppe Fanin, 40 I-40127 Bologna Italy Phone: +39-051-209-6204 Fax: +39-051-209-6203 "Fatti non foste a viver come bruti, ma per seguir virtute e canoscenza" Dante Alighieri - Inferno - Canto XXVI "Ihr seid bestimmt, nicht Tieren gleich zu leben, Nein, Tugend zu erringen und Erkenntnis" "Ye were not form'd to live the life of brutes, But virtue to pursue and knowledge high"
