extracting a .tar.bz2.sig file

[gazz1982]

I have a file ending .tar.bz2.sig

I tried:

sudo tar -xvjf freetype-2.3.11.tar.bz2.sig -C /usr/local/src/


but it returned:

bzip2: (stdin) is not a bzip2 file.
tar: Child returned status 2
tar: Exiting with failure status due to previous errors

I have installed GNU Make but I am now stuck, any ideas?

Thanks

Google: what is a .tar.bz2.sig file

...whether the signature file matches the source file...
