I'm working with my coding partner remotely on a module we're developing. Its a CGI::App based web interface.

We're using CGI::Application::Plugin::Config::Simple to read in configuration data, including a definition for library, where our respective sandboxes are stored.

Its loading the cpan installed modules already in @INC, just fine. But its tripping up on this piece of it:

# cgiapp_init();
sub cgiapp_init {
  my $self = shift;
  $self->config_file('/var/lib/cf/tbd/regform/Registration.ini');
  my $lib = $self->config_param('library');
  use lib qw/$lib/;
  use Registration::WWW::htmlgui;
  use Registration::DB;
  my $dbh = Registration::DB->connect($self->config_param('db_engine'),$self->config_param('host_name'),$self-
>config_param('db_name'),$self->config_param('db_user'),$self->config_param('db_pw'));
  my $result = auth_config($dbh);
}

At which point it throws these ugly errors, reading:

Use of uninitialized value in string at Registration/lib/Registration/WWW/RegForm.pm line 46.
Empty compile time value given to use lib at Registration/lib/Registration/WWW/RegForm.pm line 46

Apparently it wants to be able to do its use lib piece at compile time, but it doesn't get populated from the configuration until run time. Can anyone here suggest a work-around, please?

All help appreciated.
