Hi list, I'm installing OTRS in RedHat Enterprise 4, with Apache2 and mod_perl_1.99. I've facing some problems but finally I've a system running except that I can't add packages and that's really what I need (want to install SIRIOS modules). The error I get when clicking in [Package Manager] is: Software error: Can't locate HTTP/Request/Common.pm in @INC (@INC contains: ../../ /opt/otrs/Kernel/cpan-lib /opt/otrs/ /usr/lib/perl5/vendor_perl/5.8.5/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.5 /usr/lib/perl5/5.8.5/i386-linux-thread-multi /usr/lib/perl5/5.8.5 /usr/lib/perl5/site_perl/5.8.5/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.4/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.3/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.2/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.1/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.5 /usr/lib/perl5/site_perl/5.8.4 /usr/lib/perl5/site_perl/5.8.3 /usr/lib/perl5/site_perl/5.8.2 /usr/lib/perl5/site_perl/5.8.1 /usr/lib/perl5/site_perl/5.8.0 /usr/lib/perl5/site_perl /usr/lib/perl5/vendor_perl/5.8.4/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.3/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.2/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.1/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.0/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.4 /usr/lib/perl5/vendor_perl/5.8.3 /usr/lib/perl5/vendor_perl/5.8.2 /usr/lib/perl5/vendor_perl/5.8.1 /usr/lib/perl5/vendor_perl/5.8.0 /usr/lib/perl5/vendor_perl . /etc/httpd/ /etc/httpd/lib/perl //../.. //../../Kernel/cpan-lib) at /usr/lib/perl5/vendor_perl/5.8.5/LWP/UserAgent.pm line 409, <PRODUCT> line 24. For help, please send mail to the webmaster (..) , giving this error message and the time and date of the error. But the point is that Common.pm file IS in the system: # locate Common.pm /usr/lib/perl5/vendor_perl/5.8.5/i386-linux-thread-multi/Apache/TestCommon.pm /usr/lib/perl5/vendor_perl/5.8.5/HTTP/Request/Common.pm Anyone has any idea, or has faced the same problem? Thanks Rafa.
