Subject: Installing rb-gsl-1.7.0 on Windows

Maybe I'm being dense but I'm trying to install GSL on Windows.

I'm trying to take the precompiled route with the rb-gsl-1.7.0 tarball 
(http://codeforpeople.com/lib/ruby/rb-gsl-win/) and I unzip it into 
c:/rb-gsl-1.7.0.  The instructions specify that the gsl-config must be 
in the search path so I ensure that my path has my ruby executable 
(1.8.4) and has the rb-gsl-1.7.0 directory included.

Yet, when I execute the setup I get the following:

checking gsl version... C:/rb-gsl-1.7.0/ext/extconf.rb:143: Check 
GSL>=0.9.4 is
installed, and the command "gsl-config" is in search path. 
(RuntimeError)
setup.rb:535:in `command': 'system c:/ruby/bin/ruby 
C:/rb-gsl-1.7.0/ext/extconf.
rb ' failed (RuntimeError)

Is my gsl-config not in the path somehow?  Or do I need some other GSL 
package previously installed?  Should I be install through MS command 
prompt, or Cygwin (I've tried both, same message).

Alternatively, I've tried compiling my own binaries through Cygwin and 
I'm still waiting for those to finish compiling, but when I did it the 
first run through I didn't specify the prefix (which I figure messed it 
up).

Anyway, any information you can provide as far as getting GSL onto my 
Windows environment would be great.

Thanks,

Andrew
