You do not appear to have perl on your system. Even though perl is not required
for using magicrescue, you should be aware that many of the included recipes
and tools require it.

You have perl on your system, but invoking it with "/usr/bin/env perl" does not
work. Unless your system is completely broken or nonstandard, please report
this issue.
In the mean time you need to change the first line of all the included perl
scripts you wish to use, if any.

You have perl, but support for large files is not enabled. You should either
recompile perl with -Duselargefiles or chop your files into 2GB pieces to use
any of the recipes that require perl.
