[rrd-developers] rrdtool-1.3.99909060808 configure error

[Barrie]

Hi Tobi,

Thanks. I'll try and get this worked out. It seems that the new version 
of ruby on Windows has been compiled with Mingw32 instead of Microsoft 
Visual C++. To get the Ruby binding for Ruby v1.9.1 compiled for rrdtool 
in Windows, it seems that I need to compile rrdtool with MinGW32.

I'll let let you know of the progess.

Thanks.

Cheers, Barrie
