好吧，过去两天我一直在尝试完成这项工作，重新安装依赖项，更新模块，但我还没有找到任何解决方案。
安装命令行：
$> cpan DBIx::Class::Schema::Loader
我得到了失败的测试，例如：

更新
正如 abraxxa 所建议的，我尝试了一个更新的 perl 版本：
icsl8684> perl -v
This is perl 5, version 12, subversion 2 (v5.12.2) built for x86_64-linux
另外，我使用 local::lib 因为我没有 root 权限。我重新运行测试，它们再次失败。但是，我没有看到 perl 版本在 cpan 安装过程中发生了变化：
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'

# Column 'dbix_class_testcomponent' in table 'loader_test2' collides with an inherited method.
# See "COLUMN ACCESSOR COLLISIONS" in perldoc DBIx::Class::Schema::Loader::Base .

第一行是使用/usr/bin/perl而不是
~/.perl/perl
我已经更改了我$PATH以使用更新的 perl 版本，确实如此（参见 perl -v 行）。
我感觉这里有些不对劲。我还尝试安装cpan[5]> install Devel::DProf并收到以下错误：无法为模块Devel加载'~/.cpan/build/Devel-DProf-20110802.00-cJFc6O/blib/arch/auto/Devel/DProf/DProf.so':: DProf：~/.cpan/build/Devel-DProf-20110802.00-cJFc6O/blib/arch/auto/Devel/DProf/DProf.so：未定义符号：get_cvn_flags at /usr/lib/perl5/5.8.8/x86_64-linux -thread-multi/DynaLoader.pm 第 230 行。在 dprof/test8_t 第 0 行。
如您所见，它尝试从 /usr/lib/ 而不是我拥有的 local::lib 加载 DynaLoader。
