    Hi,

    I realise this issue isn't "new", but my main problem is finding out
    how to resolve the issue, short of upgrading from Woody to Sarge,
    which is something that I need to plan carefully (cloning HDD for a
    "test upgrade" and all that) :P

    Basically, I recently upgraded apache, mysql & php using http://
    www.dotdeb.org. However, the upgrade of apache broke a script which
    relied on DBI, which in turn relies on mod_perl.

install_driver(mysql) failed: Can't load '/usr/lib/perl5/auto/DBD/ 
mysql/mysql.so' for module DBD::mysql: /usr/lib/perl5/auto/DBD/mysql/ 
mysql.so: undefined symbol: PL_perl_destruct_level at /usr/lib/perl/ 
5.8.0/DynaLoader.pm line 225.

Perhaps a required shared library or dll isn't installed where expected

Line 19:-
my $dbh = DBI->connect("DBI:mysql:$db_name:$db_hostname",  
$db_username, $db_password)
     or die "Couldn't connect to database: " . DBI->errstr;
------
Investigating this issue, it seems that _somehow_ Perl 5.8.0 was  
installed on the Woody server I admin. (we took over this server from  
previous owners, and I don't think the server was wiped clean - this  
was before my time so..). Checking around, I'm frankly puzzled as to  
how Perl 5.8.0 was installed. Anyway, since Perl 5.8.0 is installed,  
it would cause too much problems to downgrade back to 5.6.0 (broken  
scripts and all that).
The main problem is that I cannot simply do a "dselect" & reinstall  
"libapache-mod-perl", because as far as I can tell, the woody stable  
version of "libapache-mod-perl" requires Perl 5.6, whilst I somehow  
have Perl 5.8...
Any thoughts & suggestions as to how I can get DBI to work without  
errors for now, till I do a proper upgrade to Sarge?
Deepest thanks,
Yoav
