Slic3r error

In previous post things became a little disjointed, so Im starting over making the problem more simplified.
I can navigate to the Slic3r folder and try to run slic3r and get the following error. Like I said Im a total noob so please be explicate with any helps, thanks.

dave@ubuntu-desktop:~/reprap/Software-master/slic3r$ ./slic3r.pl
Can't locate Boost/Geometry/Utils.pm in @INC (@INC contains: /home/dave/reprap/Software-master/slic3r/lib /etc/perl /usr/local/lib/perl/5.14.2 /usr/local/share/perl/5.14.2 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.14 /usr/share/perl/5.14 /usr/local/lib/site_perl .) at /home/dave/reprap/Software-master/slic3r/lib/Slic3r.pm line 32.

So then I tried:

sudo cpanm Boost::Geometry::Utils Math::Clipper \
Math::ConvexHull Math::ConvexHull::MonotoneChain Math::Geometry::Voronoi Math:lanePath Moo Wx XML:AX

and end up with:

Math::ConvexHull is up to date. (1.04)
Math::ConvexHull::MonotoneChain is up to date. (0.01)
Math::Geometry::Voronoi is up to date. (1.3)

So I went cpan.org/~smueller/ExtUtils-ParseXS/ and downloaded ExtUtils-ParseXS-3.18_03, but when I try to extract it it tells me it doesnt look a tar archive and aborts.
Am I on the right track and what am I missing here,please?

OMG yes it works!
For those with the same problem, delete all files and folders, or rename containing slic3r.
Then follow source download instructions here:
http://slic3r.org/download
ignore the part underneath that talks about installing other crap first. Just do the top four lines and it works, installs everything checks everything.
When your finished you can enter slic3r with ./slic3r.pl and it will work!
