[sf-perl] upgrade hell?

[David Alban]

greetings,

our sysadmins are turning out boxes now which run perl 5.10.1 whereas
all of our tooling has long run on boxes running 5.8.8.  our tools
that use non-core modules get errors like:

/usr/bin/perl: symbol lookup error:
/nas/reg/lib/perl/x86_64-linux-thread-multi/auto/Data/Dumper/Dumper.so:
undefined symbol: Perl_Tstack_sp_ptr

it appears that we have some choices.

* downgrade the new boxes to 5.8.8
* put 5.8.8 on /some/network/filesystem and change "#!/usr/bin/perl"
to "#!/some/network/filesystem/bin/perl" in our tools
* reinstall all of our cpan modules on the 5.10.1 boxes (well,
actually on a nas.  the current ones are also on a nas.)

poll:  have you faced this?  what did you do?  what worked / didn't work?

old systems:

This is perl, v5.8.8 built for x86_64-linux-thread-multi

new systems:

This is perl, v5.10.1 (*) built for x86_64-linux-thread-multi
