to you happend, what happens to every unix system administrator sooner
or later. You used the power of "rm -rf".
Generally you should be _very_ careful about issueing "rm -f" at all.
If a "-f" and wildcards are in the game it is like doing surgery on the
open heart. :)

Be absolutely sure what your commands do.
I test every unpacking command first, if operating under
tar -tvmlzf file.tar.gz
usually tests it.

I testdrive superuser rm commands with a
If you actually did a "rm -rf /bin" then you targeted the root "/bin"
directory. You wanted a "rm -r ./bin" (being in the right directory)
or an "rm -r /usr3/bin".

Next time, unpack the stuff not as root, but as a new user for this
purpose and in its own directory, like you did. E.g. create "grass" as user
and as group. As "grass" you cannot eliminate root's files.
You might need to set a few paths after installation being root, but it
generally is worth the trouble.
And be more carefull with your superuserpowers.
