Hi Brad, I'm not sure I understand the full sequence of events, but I'd definitely recommend re-installing from the binary installer. Building from source is possible, of course, but once you run into a problem it's a lot harder to guess what's wrong.

I am able to load ifeffit and execute commands, however when I try to load any of the ancillary programs there are failures (see printout below).

It looks like the core ifeffit is installed fine, but not the perl libraries needed by athena, artemis, etc. Do you have any ideas why that might be the case? What, if anything, is in /Library/Perl?

As per previous posts, I've installed and updated g77 via fink, as well as tk and tk::pod via cpan. I also had to install LWP via cpan before I could get ifeffit to run.

OK.... but none of this should be needed for athena to run.

From the install notes I see that ifeffit's intall program trashes the LWP directory in perl,

Hmmm, where do you see this? (and I'd hope it doesn't trash anything!!) The installer does write a bunch of perl modules to /Library/Perl.

so I'm curious if I've caused this problem myself (and if so, how do I fix it?). Secifically, the ifeffit.pm and Tk/Pod.pm files cannot be found anywhere in the @INC directories. Also, running the locate command I cannot find the files on the drive anywhere else.

They should be in /Library/Perl.

Additionally, I tried to download and re-install ifeffit from the disk image and it cannot install - the error says "you cannot continue. there is nothing to install."

You probably need to delete the "installation receipt" by removing the /Library/Receipt/Ifeffit-1.2.*****.pkg folder(s). Then you should be able to do a full re-install. After that happens, check the contents of /Library/Perl. Hope that helps. Let us know how it works out. Cheers, --Matt
