script generates uninitialized variables

Use of uninitialized value $infoPFSMemory[0] in substitution (s///) at
    /usr/bin/mysqltuner line 2927 (#1)
    (W uninitialized) An undefined value was used as if it were already
    defined.  It was interpreted as a "" or a 0, but maybe it was a mistake.
    To suppress this warning assign a defined value to your variables.

    To help you figure out what was undefined, perl will try to tell you the
    name of the variable (if any) that was undefined. In some cases it cannot
    do this, so it also tells you what operation you used the undefined value
    in.  Note, however, that perl optimizes your program and the operation
    displayed in the warning may not necessarily appear literally in your
    program.  For example, "that $foo" is usually optimized into "that "
    . $foo, and the warning will refer to the concatenation (.) operator,
    even though there is no . in your program.

Server version: 5.1.73
I assume this because absence of performance_schema is not handled properly

No sure but next errors: should be fixed in the next commit.

Last version should fix this ....

[vchepkov]

Yes, it did, thank you. Could you bump version number, please?

[vchepkov]

By the way, rpm complains about this string:

%changelog
* Thu Jan 5 2015 Jean-Marie RENOUARD <jmrenouard@gmail.com> %VERSION%-1

That's because Jan 5 2015 was Monday :)

[jmrenouard]

@vchepkov can you give us your feedback ?

[vchepkov]

I thought I did, sorry if I wasn't clear in my comment above
Yes, fix worked perfectly, thank you.
