Such CPAN site incompatibilities are so common, there there exists
even a simplier solution for this:
perl -MCPAN -e'recompile'
Quoting perldoc /usr/lib/perl5/5.10/CPAN.pm
recompile() is a very special command in that it takes no argument and
runs the make/test/install cycle with brute force over all installed
dynamically loadable extensions (aka XS modules) with 'force' in
effect. The primary purpose of this command is to finish a network
installation. Imagine, you have a common source tree for two different
architectures. You decide to do a completely independent fresh
installation. You start on one architecture with the help of a Bundle
file produced earlier. CPAN installs the whole Bundle for you, but when
you try to repeat the job on the second architecture, CPAN responds
with a "Foo up to date" message for all modules. So you invoke CPAN's
recompile on the second architecture and you're done.
Another popular use for "recompile" is to act as a rescue in case your
perl breaks binary compatibility. If one of the modules that CPAN uses
is in turn depending on binary compatibility (so you cannot run CPAN
commands), then you should try the CPAN::Nox module for recovery.

Hmm, I would like to know that also.
So far I only saw the Params::Validate problem with DateTime-Locale.
It could be any of these current issues, but most have different failures.
test FAIL ack-1.84 (permission problem)
test FAIL PAR-Packer-0.980
test FAIL Archive-Rar-2.02
test FAIL Class-MOP-0.62
test FAIL DateTime-Locale-0.4001 - old Params::Validate in site
test FAIL Devel-Tokenizer-C-0.07
test FAIL Devel-TypeCheck-1.2
test FAIL GraphViz-2.03
test FAIL Log-Dispatch-2.21
test FAIL Log-Log4perl-1.16
test FAIL Log-Report-0.18
test FAIL MP3-Find-0.03
test FAIL Net-Daemon-0.43
test FAIL Perl-Critic-1.088
test FAIL Text-RecordParser-v1.2.1
test FAIL Readonly-XS-1.04 - This looks suspect also
test FAIL PerlIO-gzip-0.18
But
$ for p in $(egrep "test FAIL.*perl-5.10.0 patch 34065" reports-sent.db |\
perl -ane'print $F[2],"\n"'); do grep "test PASS $p" reports-sent.db; done
only gives me:
test PASS DateTime-Locale-0.4001 (perl-5.10.0 patch 34065)
cygwin-thread-multi-64int 1.5.25(0.15642)
So the recompile of all my binary site XS modules only fixed the
DateTime-Locale-0.4001 issue.
