Hi Kyle, 

I've seen the same message with Perl 5.30 on Fedora 32 as well.  I believe you need to do:
    perl -I. Build.PL

That is, explicitly tell Perl to look in the current folder for files to import.

Good luck with the build though -- I haven't built it successfully on Fedora32 yet, but I have not tried in a few months.   You may also find some of the hints by Vasily Lebedev at https://github.com/bruceravel/demeter/issues/62 and links therein to Pastebin configs and hacks to get Demeter to build.

I recently successfully installed the Demeter suite on my Linux Mint 19 machine. Last week, I updated to Linux Mint 20, and now I get the following error when trying to run athena from the command line:

Can't locate Demeter/Here.pm in @INC (you may need to install the Demeter::Here module) (@INC contains: /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.30.0 /usr/local/share/perl/5.30.0 /usr/lib/x86_64-linux-gnu/perl5/5.30 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl/5.30 /usr/share/perl/5.30 /usr/local/lib/site_perl /usr/lib/x86_64-linux-gnu/perl-base) at /usr/local/bin/dathena line 7.
BEGIN failed--compilation aborted at /usr/local/bin/dathena line 7.

I was wondering if there was a relatively easy way to fix this, or if the best recourse is to simply reinstall Demeter? It took some fiddling to install initially, so I don't want to reinstall it unless that's the easiest way to fix the issue.

Also, the mailing list link on the Demeter home page (http://cars9.uchicago.edu/mailman/listinfo/ifeffit/) times out. Fortunately I was able to get a working link (https://millenia.cars.aps.anl.gov/mailman/listinfo/ifeffit) from a friend.

Sincerely,

Kyle Kluherz
