I have spent some time googling for answers to this and I have checked
this forum's archives for hints. I am either using the wrong terms or
not understanding what I am reading. Here is what happened:
I am playing around to find out how to download from finance.google.com,
parse the results and then do a linear regression.
I found curb, csv and gsl (rb-gsl that is) to be the gems required.
As I started to develop some code I first required curb, ran the code
with -w flag and all was fine, no warnings.
I developed the parser, required csv and ran code with -w flag and all
was fine, no warnings.
I had to install gsl and rb-gsl gem, which was a hassle, as I first
installed gsl excluding shared libraries (as the INSTALL document for
Mac OS X would state) but that turned out to prevent gem install gsl
from going through. After I reinstalled gsl without any ./configure
options, gem install gsl went through smoothly.
But once I ran my code again with the -w flag suddenly the following
warnings appear:
$ ruby -w goodtest.rb

I commented out all requires (require "curb", require "csv", require
"gsl") and then re-added them one by one. "csv" did not trigger the
warning, but curb and gsl did.
I have seen circular requires been discussed as bugs, but since I did
not have them before my troublesome install of gsl and rb-gsl I am not
sure whether this is a bug or whether I am doing something wrong.
Any help would be much appreciated.
