Hello again, I tried to install the new package of both ifeffit(1.2.11) and horae (0.67) but it also didn't work. I first removed any file related to ifeffit and horae that I could find. Pgplot, ifeffit, Xray-Absorption, Xray-Scattering and Chemistry-Formula installation runned without error and I could open ifeffit on command line. But the error mensage below appeared when I runned the "perl Build.PL" on horae. ... Checking whether your kit is complete... Looks good Checking prerequisites... Package 'Config::IniFiles' already declared with version '2.39', ignoring subsequent declaration. Looks good Deleting Build Removed previous script 'Build' Creating new 'Build' script for 'horae' version '067' ... Even though this error I runned ./Build and ./Build install and no error appeared. But when I tried to run athena (it also happens on artemis) the error appeared: ......

BEGIN failed--compilation aborted at /usr/bin/athena line 67. ..... I looked for the Ifeffit.pm file on /usr/lib/perl5 and it doesnt exist. Thanks, Gilberto ps: I will write on the FAQ as soon as possible... :)
