Re: @INC problem with SOAP::Lite

[almut]

Not really sure, but my guess would be that it has to do with the following piece of code (SOAP/Lite.pm, line 2500):

  unless (defined(%{"${class}::"}) || exists($INC{join '/', split /::/
+, $class.'.pm'})) {
    # allow all for static and only specified path for dynamic binding
+s
    local @INC = (($static ? @INC : ()), grep {!ref && m![/\\.]!} $sel
+f->dispatch_to);
    eval 'local $^W; ' . "require $class";

    die "Failed to access class ($class): $@" if $@;
    $self->dispatched($class) unless $static;
  }

in particular the local @INC = ...

A cursory glance at the surrounding lines makes me wonder what would happen if you "preload" Data::Dumper in the server (the idea being that it then already is loaded when the require is executed with the restricted @INC...).   Just an idea - could be entirely wrong, though.
