I finally got all the stuff back up and running last night under
mod_fastcgi. No encantation I could find (--enable--embeddable, static
linked lib, etc) would cure the segfaults when preloading Image::Magick.
 In the end, I just ended up ditching mod_perl since it's not really a
requirement for the sites in question.
