I have been trying to figure out this problem for a few days now... I am trying to install a set of dependent modules for mogilefs. Yesterday, I was hung up on installing IO::AIO due to error: undefined symbol. I forget specifically what symbol, but google says it's a method in the perl API. After chatting with people in the chatterbox, it was decided that I needed to upgrade from Perl 5.8.8 to 5.10. - Now I have done that, and I have installed IO::AIO seemingly successfully, and I'm getting hung-up on the next module: Gearman::Client::Async - same basic problem: 

Running make test
PERL_DL_NONLAZY=1 /usr/local/bin/perl "-MExtUtils::Command::MM" "-e" "
+test_harness(0, 'blib/lib', 'blib/arch')" t/*.t
t/allinone........Can't load '/usr/local/lib/perl5/5.10.0/x86_64-linux

another symbol that should be in the perl API... what gives? this is driving me mad. This is a Brand spanking new Debian Etch amd64 machine. Completely fresh out of the box. These are the packages I have updated via apt-get: 

apt-get install
    openssh-server
    build-essential
    libmysqlclient15-dev
    subversion

[download]

then I downloaded and compiled, make, make test, make install: 
perl-5.10.0.tar.gz

[download]
Then installed: 
perl -MCPAN -e shell;
install IO::AIO - seemed to work fine
install Gearman::Client::Async - FAIL (see msg above)

[download]
Please Help?
