I don't know why exactly RandomAccess.pm isn't found for you - perhaps
it's not in any of the directories in @INC. You may copy it to one of
those directories.
However, we actually have our own copies of ExifTool.pm and
RandomAccess.pm in JtR under run/lib, and pdf2john.pl tries to look for
them (also) in the "lib" subdirectory relative to where the script
itself is located. So you may want to either run the command when
you're in JtR's "run" directory, or copy not only pdf2john.pl but also
"run/lib" (naming it just "lib") to C:\Strawberry.
Yet another option is to install Cygwin and also install its
perl-Image-ExifTool via Cygwin's setup program (it lets you select
package groups or packages).
https://cygwin.com/cygwin/packages/summary/perl-Image-ExifTool.html
and then run pdf2john.pl from Cygwin shell.
