Hi,
You can try extending @INC. add the line: unshift @INC, "/{insertFullPathHere}/Kernel/cpan-lib/Net/DNS/"; to index.pl, this way you will search that directory first while using index.pl. Would that do what you need? Hope this helps. Too bad, the original error "Modification of a read-only value attempted at /usr/lib/perl5/ site_perl/5.8.8/i686-linux/Net/DNS/Question.pm line 47." still points to the use of the system-wide module ....
I think unshift'ing is the right way, but you have to pass the "basic" path for your module. Something like this in index.pl: unshift @INC, "$Bin/../../Kernel/cpan-lib"); # without "Net/DNS/" push (@INC, "$Bin/../.."); # no more need to push $Bin/../../Kernel/cpan-lib and then directly after that log the versions: use Net::DNS::Question; warn "Net::DNS::Question: $Net::DNS::Question::VERSION\n"; warn "Net::DNS::Resolver::Base: $Net::DNS::Resolver::Base::VERSION\n"; that should give you 610 versions from cpan. Another thing just crossed my mind: since I'm working on a non-production system (just testing), I don't know for sure if these versions are working. Maybe someone else can test for her/his versions? perl -MNet::DNS::Question -e 'print "v=$Net::DNS::Question::VERSION\n";' and perl -MNet::DNS::Question -e 'print "v=$Net::DNS::Resolver::Base::VERSION\n";' prints the version on a shell Greetings, Gerhard
