 Description   

Scripts '/usr/bin/wsrep_sst_xtrabackup' and '/usr/bin/wsrep_sst_xtrabackup-v2' are part of 'mariadb-galera-server' and they use 'socat' command. If 'mariadb-galera-server' is installed on the fresh system wich does noit have 'socat' package installed node joining operation failed.

Steps to reproduce:
1. use two fresh CentOS6 or Debian7 machies to create a cluster
2. install 'mariadb-galera-server' package on both
3. start node1
4. try to join node2 to the cluster

Expected result: two-nodes cluster is running

Actual result:
node2 start operation failed
log contains:
WSREP_SST: [INFO] Using socat as streamer (20140505 14:32:41.368)
*which: no socat in
(/usr/sbin:/sbin:/usr//bin:/sbin:/usr/sbin:/bin:/usr/bin:/usr/bin)**
**WSREP_SST: [ERROR] socat not found in path:

Note: CentOS6 default repositories does not contain 'socat' package. It is available from EPEL repo. Should it be mentioned somewhere in README?

It would be good to check if scripts are using other commands that are not mentioned in the dependecy list (even 'sudo' is not installed by default in some distributions)
nc, grep, rsync, tar, gawk, findutils, sed? coreutils util-linux curl net-tools?

one note regarding dependecy on 'nc package: in Debian7 default nc is netcat-traditional which gives an error "nc: invalid option – ‘d’” in the sst.err log file. Fixed by installing netcat-openbsd package. Should it be also reflected in the mariadb-galera-server package dependecy list?

This problem still exists in MariaDB-server-10.1.12 and 10.1.13 on CentOS 6.7. Here is my logs from second empty Galera node:

I had to install "socat" manually from EPEL to fix this.
