Problem compiling in Active Perl 5.8

[zatlas1]

Hi I've just installed the latest Perl 5.8.x from Activeperl. I run
the thing under the latest Open Perl IDE 1.0.x. I had not have any
problems when I used Perl 5.6. Now I try to compile a program that was
compiled with no problems previously. I get compile errors in some
internal program "package Cwd;" the statement says "use Carp;" and the
errors are:
" No DB::DB routine defined at C:/Perl/lib/Cwd.pm line 151. BEGIN
failed--compilation aborted at C:/Perl/lib/Cwd.pm line 151.
Compilation failed in require at ..\Perl/perl5db.pl line 39. BEGIN
failed--compilation aborted at ..\Perl/perl5db.pl line 39. Compilation
failed in require. BEGIN failed--compilation aborted."
could somebody guide me what should I do. Is 5.8 a stable and reliable
version or should I go back to 5.6. Is Active Perl a complete and
reliable distribution? If not, how do I get the missing pieces or
alternatively get a better product (I use Perl for production support
- I do not do experiments).
Thanks ZA
