As you are a company call a consultant :-) Or ...

tar command varies from one Unix to another,
j parameter is to specify to unpack bz2,
but j may not be recognised,
to see if j is supported by your tar, type & read 
	man tar
if not supported either install a better tar, or easier:
	bzip2 -d gnupg-2.0.20.tar.bz2

then next problem:
I presume what you downloaded is sources, so you will need to compile
them first.

After you understand man tar do this
	mkdir gnupg-2.0.20
	cd gnupg-2.0.20
	tar xvf ../gnupg-2.0.20.tar

Then as always, one of the file names beginning with a capital
	ls [A-Z]*
will tell you how to build & install binaries
