I don't believe that is the entire output of install PDF::OCR2. Please re read the documentation linked to previously, if you have any problems post the actual output of the cpan install command. See Writeup Formatting Tips and How do I post a question effectively?.

This is the exact error

As mentioned in the INSTALL file (third time it's been mentioned to you so far), you need to install these modules. So either install them manually or launch cpan and type:

o conf prerequisites_policy follow
o conf commit
[download]

Which should install prerequisites for modules when you try to install them, so:

cpan> install PDF::OCR2
[download]

Should install these for you. See the CPAN documentation along with Installing Modules from the tutorials section of this site.

Also,
