I don't think "Didn’t find shared library" is the precise output (and that 
does not help diagnosis here) and I'm not sure that you are running the 
correct 'extract' binary.  What do you get if you type

$ which extract

and 

$ extract -v

Also, try this (and exactly this, and please report the exact output, not your 
interpretation thereof):

$ ldd -r /usr/local/lib/libextractor/libextractor_pdf.so
$ export LIBEXTRACTOR_PREFIX=/usr/local
$ /usr/local/bin/extract dmca.pdf
$ /usr/bin/extract -v
$ /usr/local/bin/extract -v
$ ls -al /usr/local/lib/libextractor.so

Thanks!
