Bug#620550: libapache2-mod-perl2: Perl tie() interface does not work after dist-upgrade from lenny -> squeeze

Package: libapache2-mod-perl2
Version: 2.0.4-7
Severity: important


After upgrading from lenny to squeeze calls to tie() from code running in mod_perl 2 are failing. 

The following code works fine from the command line but the tie() fails silently when running in mod_perl 2:

print STDERR "$0: GDBM_File::VERSION is $GDBM_File::VERSION\n";
sleep 1;
my %sec;
tie(%sec,'GDBM_File',$secdbf,GDBM_READER,0640);
print STDERR "$0: key: $_\n" foreach keys %sec;
untie %sec; 

The tie fails for both GDBM and MLDBM databases. 

We've been unable to reproduce this error on systems that were installed from the latest squeeze CDs, it only 
happens on systems that were migrated from lenny to squeeze. 

As a troubleshooting measure I added print statements to gdbm_open() in gdbmopen.c and installed my own 
compiled version of the GDBM library but gdbm_open() is never called. Straces from systems that are not working
confirm that.
