Can't locate object method "new" via package "Image::Magik" (perhaps you forgot to load "Image::Magik"?) at make_thumbnail.pl line 22 (#1) (F) You said to do (or require, or use) a file that couldn't be found. Perl looks for the file in all the locations mentioned in @INC, unless the file name included the full path to the file. Perhaps you need to set the PERL5LIB or PERL5OPT environment variable to say where the extra library is, or maybe the script needs to add the library name to @INC. Or maybe you just misspelled the name of the file. See perlfunc/require and lib.
