Hi,

Some of my applications that use ruby-gnome2 require a recent version
of the following libraries installed:

libart_lgpl
libgnomecanvas
ruby-gnome2

I'd like to be able to check to make sure that the necessary libraries
are installed before the GUI is loaded, and if they're not, then spit
out some message to the user and quit.

So what are my options?

Thanks,
Joe
