Note that Apache::Reload operates on the current context of @INC. Which means, 
when called as a Perl*Handler it will not see @INC paths added or removed by 
Apache::Registry scripts, as the value of @INC is saved on server startup and 
restored to that value after each request. In other words, if you want 
Apache::Reload to work with modules that live in custom @INC paths, you should 
modify @INC when the server is started. Besides, 'use lib' in the startup 
script, you can also set the PERL5LIB variable in the httpd's environment to 
include any non-standard 'lib' directories that you choose. For example, to 
accomplish that you can include a line:

   PERL5LIB=/home/httpd/perl/extra; export PERL5LIB

in the script that starts Apache. Alternatively, you can set this environment 
variable in httpd.conf:

   PerlSetEnv PERL5LIB /home/httpd/perl/extra
