Here's another variant without the warnings weighing in at 160 bytes. 
The |$n| in the proc is something I didn't expect to work, but did...

def b
"#{$n>0?$n: 'No more'} bottle#{'s'if $n!=1} of beer"end
99.downto(1){|$n|w=" on the wall";puts b+w,b,"Take one down, pass it around
";$n-=1;puts b+w+'.'}

def b
"#{N>0?N: 'No more'} bottle#{'s'if N!=1} of beer"end
(N=99).times{w=" on the wall";puts b+w,b,"Take one down, pass it around
";N-=1;puts b+w+'.'}

Just knocked it down to 152. Output is kind of ugly, bit it works (complete
with warnings!)

[165, by my count?]

Not entirely; the original poster asked for a comma after ``around''
and an empty line in between the iterations. That costs you 5 bytes (a
double '\n' in a puts).

But, in the same way, ``more'' is not required, which saves you 5 bytes.

You've got to be careful with these things :)

NB:

def b(n)"#{n>0?n: 'No'} bottle#{'s'if n!=1} of beer"end
99.downto(1){|n|w=" on the wall";puts b(n)+w+", #{b n}\nTake one down, pass
it around,\n#{b(n-1)+w}.\n\n"}

Is only 163 bytes.
