Hi Andy,
I pulled down the updated install_perl_libs.pl and used alongside the 2.2.1
management node release. I did notice that libwww was installed to satisfy
dependencies for perl-xml-simple. I didn't do any other tweaking -- just
ran the script and otherwise followed the normal management node install
procedure.
A block allocation didn't work, however:

I updated install_perl_libs.pl in the repository:
https://svn.apache.org/repos/asf/incubator/vcl/trunk/managementnode/bin/install_perl_libs.pl
You should now be able to run it without having to perform any
additional steps. Please give it a try.
Thanks,
Andy

All,
I've managed to get around the CRITICAL error I was seeing in the vcld
log
during block allocations. perl-libwww-perl wasn't installed. *sigh*
Installing that prior to running install_perl_libs.pl solved the
problem
(should that be added to the install_perl_libs script?). I noticed that
there are two listings of PERL-related software required for the
management
node:
https://cwiki.apache.org/confluence/display/VCL/VCL+2.2.1+Management+Node+Installation
and
https://cwiki.apache.org/confluence/display/VCL/Apache+VCL
We might want to consolidate those. I was running from the install docs
and didn't even think to check that perl-libwww-perl was installed.
Prior to this, I'd developed a manual workaround, installing RPC-XML 0.71
(which is NOT the most recent version) using the make method from the
CPAN
archive.
Note that I'm on CentOS 5.7, clean install and fully updated prior to
install VCL management node. There is no package perl-XML-RPC (called
from
the script) available from the repos (with EPEL enabled),
and perl-libwww-perl wasn't installed by default.
Here's the process I used...
1. Used the 2.2.1 release install_perl_libs.pl script
2. Commented out the line that tells install_perl_libs.pl to retrieve
RPC::XML from CPAN (line 285)
3. Ran install_perl_libs.pl
4. Installed RPC-XML 0.71 from CPAN
5. Completed VCL management node install steps from the documentation
I went with the lowest-versions of the various dependencies needed by
RPC-XML 0.71, which is obviously not a best-practice... I'd appreciate
any
feedback from the list on whether that may have unintended
consequences...
Here's the dependency tree with links:
- RPC-XML 0.71 (http://search.cpan.org/~rjray/RPC-XML-0.71/)
- libwww-perl (LWP) 5.801 (
https://metacpan.org/release/GAAS/libwww-perl-5.801)
- URI 1.10 (https://metacpan.org/release/GAAS/URI-1.10) ... note
that some tests FAILED
- HTML-Parser 3.33 (
https://metacpan.org/release/GAAS/HTML-Parser-3.33)
- HTML-Tagest 3.02 (
https://metacpan.org/release/SBURKE/HTML-Tagset-3.02/)
- XML-Parser 2.31 (
https://metacpan.org/release/COOPERCL/XML-Parser-2.31)
Having the most recent perl-libwww-perl from CPAN yielded an install that
didn't include LWP::Protocol::https (and the script is trying to make an
HTTPS connection). Installing LWP-Protocol-https doesn't solve the
problem
because of stricter SSL certification requirements and hostname
verification (
http://search.cpan.org/~gaas/LWP-Protocol-https-6.02/lib/LWP/Protocol/https.pm
).
Many thanks,
Mike

You shouldn't have to install anything manually. It looks like there
are some problems with the current install_perl_libs.pl script. There
is a CPAN notest option which I added to make the script run a lot
faster. Apparently this option isn't always available. Try editing
install_perl_libs.pl and then run it again. Swap the comment from the
install line to the notest line, change:
eval { CPAN::Shell-notest(install, $perl_module) };
#eval { CPAN::Shell-install($perl_module) };
-to-
#eval { CPAN::Shell-notest(install, $perl_module) };
eval { CPAN::Shell-install($perl_module) };
Also, was epel successfully installed? Run 'yum
