cpuminer　を試してみました。こっちの方は簡単に出来ました。

手順１：
sudo yum install gcc make curl-devel
wget http://sourceforge.net/projects/cpuminer/files/pooler-cpuminer-2.3.2.tar.gz
tar xzf pooler-cpuminer-2.3.2.tar.gz
cd cpuminer-2.3.2/
./configure CFLAGS="-O3"
make

minerd が出来上がる。

手順２：
sudo yum install gcc make curl-devel
wget http://sourceforge.net/projects/cpuminer/files/pooler-cpuminer-2.3.2-linux-x86_64.tar.gz
tar xzf pooler-cpuminer-2.3.2-linux-x86_64.tar.gz

minerd が出て来る。

実行：
./minerd -a scrypt -o stratum+tcp://ltc.2chpool.com:3333 -u user_id.worker_id -p worker_password
