  Except you can't dlopen libperl.so, because it doesn't exist on the
system.  Instead, you've got to dlopen libperl.so.5.8.

  No.  That's broken.

  It's horrible.

  I'm going to update the "configure" script so that it tries to compile
using the "perl ... ldopts" flags.  If that fails, it will complain
loudly that your system is broken, and you should file a bug, or add to
a existing bug report.
