Hi, OK, I agree that a simple 'horae_update' also did not work to update thes for me. It appears that the new codes are built but not installed. This definitely did work for me: tar xvzf horae-045.tar.gz cd horae-045 perl Makefile.PL make sudo make install I believe that 'sudo horae_update' will also work. --Matt PS: Oddly, without the 'sudo', horae_update did not give a warning about installing as root. I got largely the same log file as Stefano, and also got this on the screen: print() on closed filehandle OUT at /Applications/Ifeffit/bin/horae_update line 263. perhaps this is printed to STDERR not STDOUT?? it's not in horae_update.log. Anyway, this is where the warning about trying to install as someone other than root is. The horae_update could probably use other improvements, as horae_update --force --file=horae-045.tar.gz still attempts to download the tarball, requires it to be named 'horae-045.tar.gz' and then deletes it.
