install gnash (swf player)

I was trying to install gnash player

zypper in gnash

but that won’t install everything the SWF palyer is not installed so youtube videos won’t play and my fav radio stream sounds like chipmunks when I try install Gnash-swf through apper this is what I get

 gnash-devel-0.8.11.git20130729-1.34.x86_64 requires gnash = 0.8.11.git20130729, but this requirement cannot be provided

then I tried git

git clone git://

as sugested on but when I try ./

./ line 1: dnl: command not found
./ line 2: syntax error near unexpected token `('
./ line 2: `dnl  Copyright (C) 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012' 

here’s what file look like, to me it seems like those line should be commented - but they’re not??
