Comment:

 I'll assign this to me, since I'm the ImageMagick maintainer. Not saying
 I'll resolve it immediately though.

 Additional configure arguments ''are'' needed. Auto-detecting other
 packages is ''not'' appropriate for software installed using MacPorts. It
 would mean that two users would "magically" get two different versions of
 ImageMagick, simply if one user already had librsvg installed and the
 other did not. We don't want that. We want everyone who builds a port with
 a given set of variants to get the same software (modulo major OS versions
 and processor architectures). If ImageMagick auto-detects librsvg if
 installed, we need to add configure arguments to disable librsvg
 explicitly unless this new +rsvg variant is chosen.
