You have probably downloaded the source code for it twice.
A tar file is a Tape ARchive file, a means of placing multiples files in to just one with an index.
gz and bz2 are entensions gived to files compressed wtih gzip and bzip2.
Together tar and compression is equilivent to a zip archive.
You can extract bz2s with
bunzip 2 filename and gzs with
gunzip filename.
Then you can untar with
tar xvf filename.
Its possible to combine the two ops with an extra switch to tar
man tar.
Then you will have the source code accessable to you.
cd in to the directory creating when you untarred the file. There will probably be files called something like
README and
INSTALL - read them (
less filename).
