After install Redhat 6.1+MySQL+Apache DSO+PHP,
I install mod_perl included URI,HTML::Parser,MIME::Base64,Net::FTP,Digest::MD5, and libwww,mod_perl successfully.
---------------------------------------
Then I add these lines into httpd.conf
-Location /perl-status-
SetHandler perl-script
PerlHandler Apache::Status
-/Location-
And then, httpd restart,
[]# Invalid command 'PerlHandler', perhaps mis-spelled or defined by a module not included in the server configure.
---------------------------------------
Error happened too,
-Location /perl-status-
SetHandler perl-script
PerlHandler Apache::Sandwich
