OK, since reducing my programs from over a thousand lines of code to a short snippet was not so simple, I wrote a few short snippets that show you the same problem: Program 1 (the executable): 
#!/exlibris/metalib/m4_b/product/bin/perl
use demo;
{
    my $externalObject = new demo;
}

[download]
Program 2: demo.pm - an instance is created by the executable: 
package demo;
require "wrapper";
use demo2;
sub new {
        my $class  = shift;
        my $params = shift;
        my $self = {};
        &call_httpd_exec();
        my $externalObject2 = new demo2;
}

[download]
Program 3: demo2.pm - an istance is created by demo.pm 
package demo2;
require "wrapper";
sub new {
        my $class  = shift;
        my $params = shift;
        my $self = {};
        &call_httpd_exec();
}

[download]
Program 4: wrapper - the required program: 
sub call_httpd_exec{
    print "hello world!!\n"
}

1;

When I run the executable program, I get this message: 
Undefined subroutine &demo::call_httpd_exec called at demo.pm line 8.

If I don't make demo.pm create an instance of demo2.pm there is no problem. Why do you think adding demo2.pm creates a problem?
