[Ifeffit] IFEFFIT on Tiger - confusion between Perl 5.8.1 and 5.8.6

[Brugger, Joel (SAM)]

I lost IFEFFIT after upgrading to MAC OS X 10.4 (Tiger). Apparently, this is
due to the fact that the upgrade replaced Perl 5.8.1 by Perl 5.8.6. I redid
the IFEFFIT installation (for 10.3), which created a Perl5.8.1 folder with
all the goodies. However, as the following error message shows, the system
is not happy and is looking for some stuff in the new PERL. And does not
find it. 

I'm not sure how to revert to 5.8.1, or alternatively more everything to the
new 5.8.6. Hopefully this is a trivial question :-)

Thanks for any help,

JOEL
