SVG rendering errors (linux)

When I run 'covert.exe -list format' I see this:
SVG SVG rw+ Scalable Vector Graphics (XML 2.4.19)
SVGZ SVG rw+ Compressed Scalable Vector Graphics (XML 2.4.19)

So I guess that means I'm using the internal renderer? I'm on Windows XP and ultimately am trying to compile this against the RMagick Ruby Gem for use in a Rails application. I've already figured out how to create the gem but the rendering is bad.

Do I get RSVG here: http://librsvg.sourceforge.net/? Is there an installation instruction written up anywhere? I've been compiling from the Windows Binary since I'm just trying to create a Ruby Gem and not compiling from source. Will that work if I need RSVG support?

JFYI if you would like to have some info from me...

I have similar problem on linux, ImageMagick 6.7.2-7 (I have tried newest version 6.7.3-1, too). The problem is really resolved by linking against librsvg.

See https://bugzilla.novell.com/show_bug.cgi?id=724222

(Bezier cubic seems to be nearer to middle control point -- represented by circle - and ending points are not rendered at all.)

Ahh I confused topic window -- this should have to go to "SVG rendering errors" topic. Sorry for that.
