librsvg static linking errors

[Jeroen Ooms <jeroen ooms stat ucla edu>]

I wrote some librsvg bindings for the R programming language. Things
work great on linux, but for OS-X and Windows I need to statically
link librsvg and its dependencies to create a redistributable binary R
package.

The linking step itself succeeds however loading the package fails
with the errors below. How can I debug this? Log with linker flags is
