Error Snort on Centos 7.

[Schnaidel]

Hi guys;
I have two ERROR in my installation:
1st in snort.conf
ERROR: /etc/snort//etc/snort/rules/so_rules.rules(0) unable to open rules file
"/etc/snort//etc/snort/rules/so_rules.rules": No such file or directory.
2nd in pulledpork.conf.
The specified Snort binary does not exist!
Please correct the value or specify the FULL rules tarball name in the pulledpork.conf!
at /usr/local/bin/pulledpork.pl line 1934.

I don't know how to correct it... I'm a newbie in Linux.
Thanks for the help.
