wget http://sourceforge.net/projects/cpuminer/files/pooler-cpuminer-2.3.2-linux-x86.tar.gz
And what were you seeing when it "doesn't do it to the end like it should"?
That's what I offered to help with since you may have issues with how wget is handling the sourceforge download.
wget http://sourceforge.net/projects/cpuminer/files/pooler-cpuminer-2.3.2-linux-x86.tar.gz
tar zxvf pooler-cpuminer-2.3.2-linux-x86.tar.gz
Then I enter
cd pooler-cpuminer-2.3.2-linux-x86
-bash: cd: pooler-cpuminer-2.3.2-linux-x86: No such file or directory
That is all.
minerd is the app... that means you successfully downloaded and untar'd the file.
When you get the -bash: cd: pooler-cpuminer-2.3.2-linux-x86: No such file or directory, can you do a pwd and ls -l to show which directory you're in and the contents? You may already be in there, so the No such file makes sense in that case.
If you are where I think you are, all you have to do is execute ./minerd --url http://whateverPool:8332 --user
