Message:
Implemented in CVS for next 0.11 release slightly differently.
Thanks to scripts to automate installation, OS absolute forms will now
always be used in @INC (file apache2-require.pl)
Automatic detection of Prefork/Worker is done in web server configuration
files.

Message:
Detlef Vollmann has found the solution to this problem.

If shell command > apachectl -V    # command name may be apache or apache2
reports ...  Server MPM: Prefork ... you are not concerned with the
problem.
If it reports ... Server MPM: Worker ... follow the steps below.

1. in file .htaccess-apache2, replace the line
           PerlHandler ModPerl::RegistryPrefork
   by
           PerlHandler ModPerl::Registry

2. in file apache2-require.pl, change all relative paths to absolute form,
e.g.
          , "."
          , "./lib"
    to
          , "/whatever/you/installed/lxr"       # usually
/usr/local/share/lxr
          , "/whatever/you/installed/lxr/lib/"  # usually
/usr/local/share/lxr/lib

3. in the configuration file for the web server (recommended name
lxrweb.conf), replace the line
          PerlRequire   /whatever/you/installed/lxr/apache2-require.pl    #
usually /usr/local/share/lxr/apache2-require.pl
   by
          PerlPostConfigRequire  
/whatever/you/installed/lxr/apache2-require.pl
   You may also want to activate the Perl security tests with
          PerlSwitches -T

You're done

Note: the maintainer does not use MPM Worker and has not tested the fix.
Please report if it does not work

This will be put soon in the manual and the web site.

Message:
Hello,

This problem seems to be related to the interaction between Perl and
Apache. The main difference with my configuration is "Server MPM: Prefork"
in mine.

Try with the Perl guys and tell me about it. Meanwhile, I keep this bug
open.

Regards,
ajl
