Problem Recompiling mod_perl

[Kaplan, Andrew H.]

Hi there –   I am going through the motions of recompiling mod_perl on a Red Hat Enterprise 3 server. The server was originally configured with Perl 5.8.0, but the application which I am trying to install requires Perl 5.8.3 or later. I downloaded the source code for version 5.8.8 and installed it onto the system. The server currently has two versions of Perl where the libraries for version 5.8.0 are located in /usr/lib/perl5, and those for version 5.8.8 are located in /usr/local/lib/perl5. The 5.8.0 binary was located in the /usr/bin directory. I had renamed the binary to perl_orig and created a symbolic link to the /usr/local/bin/ directory where the latter version is located.   After compiling mod_perl, I modified the httpd.conf file to include the following information:   <VirtualHost ip address:80>         ServerName hostname         ServerAdmin email address         DocumentRoot /var/opt/rt3/share/html         ErrorLog /usr/local/apache/logs/rt_error_log         ErrorLog /usr/local/apache/logs/rt_error_log </VirtualHost>   and   Alias /rt /opt/rt3/share/html     <Location /rt>         AddDefaultCharset UTF-8         SetHandler perl-script         PerlHandler RT::Mason         PerlModule Apache::DBI         PerlRequire /opt/rt3/bin/webmux.pl     </Location>   Whenever I try to start the server with the above information, I get the following error:   Syntax error on line 577 of /usr/local/apache_1.3.perl/conf/httpd.conf: Can't locate Apache/DBI.pm in @INC (@INC contains: /usr/lib/perl5/5.8.0/i386-linux-thread-multi /usr/lib/perl5/5.8.0 /usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.0 /usr/lib/perl5/site_perl /usr/lib/perl5/vendor_perl/5.8.0/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.0 /usr/lib/perl5/vendor_perl /usr/lib/perl5/5.8.0/i386-linux-thread-multi /usr/lib/perl5/5.8.0 . /usr/local/apache/ /usr/local/apache/lib/perl) at (eval 5) line 3.   Line 577 corresponds to the PerlModule Apache::DBI line. I verified the Apache::DBI module has been installed.   I tried renaming the /usr/lib/perl5 directory, and creating a symbolic link to  /usr/local/lib/perl5, but that caused the Apache server to not be able to start. The error message I got in this case is the following:   /usr/local/apache_1.3.perl/bin/httpd: error while loading shared libraries: libperl.so: cannot open shared object file: No such file or directory /usr/local/apache/bin/apachectl start: httpd could not be started   I need to recompile mod_perl to use the 5.8.8 libraries. One idea I had was uninstalling perl 5.8.0 completely from the system. Does anyone have insights into this? Thanks.
