DBIx::Class::Schema::Loader installation fails

Question

Well, I been trying to get this work for the past two days, re installing dependencies, updating modules, but I haven't found any solution.

install command line:

$> cpan DBIx::Class::Schema::Loader

I get failed tests, such as:

UPDATE

As abraxxa suggested, I tried a newer perl version:

icsl8684> perl -v

This is perl 5, version 12, subversion 2 (v5.12.2) built for x86_64-linux

Also, I use local::lib because I don't have root permission. I rerun the tests and they failed again. However, I don't see that the perl version has changed in the cpan install proccess:

PERL_DL_NONLAZY=1 /usr/bin/perl "-MExtUtils::Command::MM" "-e" "test_harness(0, 'inc', 'blib/lib', 'blib/arch')" t/*.t t/backcompat/0.04006/*.t
t/01use.t ............................... ok     
t/02pod.t ............................... ok     
t/10_01sqlite_common.t .................. 6/294 
#   Failed test 'Correct number of warnings'
#   at t/lib/dbixcsl_common_tests.pm line 323.
#          got: '10'
#     expected: '9'
# Column 'dbix_class_testcomponent' in table 'loader_test2' collides with an inherited method.
# See "COLUMN ACCESSOR COLLISIONS" in perldoc DBIx::Class::Schema::Loader::Base .
# Column 'dbix_class_testcomponentmap' in table 'loader_test2' collides with an inherited method.

The first line is using /usr/bin/perl instead of

~/.perl/perl

I have changes my $PATH to use the newer perl version and indeed it is (see the perl -v line).

I have feeling that something is messed up here. I also tried to install cpan[5]> install Devel::DProf and got the following error: Can't load '~/.cpan/build/Devel-DProf-20110802.00-cJFc6O/blib/arch/auto/Devel/DProf/DProf.so' for module Devel::DProf: ~/.cpan/build/Devel-DProf-20110802.00-cJFc6O/blib/arch/auto/Devel/DProf/DProf.so: undefined symbol: get_cvn_flags at /usr/lib/perl5/5.8.8/x86_64-linux-thread-multi/DynaLoader.pm line 230. at dprof/test8_t line 0.

As you can see, it tries to load DynaLoader from /usr/lib/ instead of the local::lib I have.

The DBIx::Class maintainers go a large way to make it downward compatible to version Perl 5.8.1 which is declared in its META file. It might be that some other components like DBD::SQLite or DBIx::Class::Schema::Loader have a bug on your specific version (RedHat Enterprise Linux 4?). DBIx::Class has even a section in its troubleshooting docs: Perl Performance Issues on Red Hat Systems

If you want to install your own Perl the recommended way is to use perlbrew. You don't even need root access, you can install it in your home directory, even multiple, completely separated installations of different or same versions, one for each app for example.
