You need to be in the directory where Image::OCR::Tesseract is unpacked.

when i ran root@web /#cpan Image::OCR::Tesseract the following error message came and it is saying cannot create MakeFile.pl...

"Found 19 old builds, restored the state of 19"

Looks like you've tried to install this a few times. You need to start reading the installation notes for modules, I don't keep telling you to do this for my benefit, I learned that lesson the first time I had to install a module. do:

cpan> clean Image::OCR::Tesseract
cpan> install Image::OCR::Tesseract

I think you may see the error message:
