Oh Gurus! I am maintaining a large Perl CGI codebase dating back to '97. Recently a script that had been working for years failed with:

Undefined subroutine &main::DB2QUERY called at E:\wwwroot\cgi-bin\chargeR4.cgi line 260

&DB2QUERY is a sub that lives in a library called db2access.pli.
db2access.pli is required at the top of chargeR4.cgi like so:

require "$REQUIRE_DIR/db2access.pli";

I printed out $REQUIRE_DIR and it is the correct path.
I also printed out _PACKAGE_ and it is in fact "main".

I am asking for any debugging advise. I suspect that there is a namespace problem. Is there a way I can dump all the package names? Could DB2QUERY be in another namespace than "main"?

Btw, I am running Active State Perl 5.8.

Thanks - Dorian
