Basically, the above line (with eval ....) is just trying to ensure
that the rest of the script gets executed as a perl script, in case
it's being executed as a sh (or bash) script instead. It's some rather
convoluted sh syntax, but I don't know why it doesn't work for you (it
could fail if it's getting evaluated by csh rather than sh). It's
pretty pointless, unless you're on an OS that doesn't understand #!
/usr/bin/env perl. I would just change it to that, since that works as
it should.
