FYI: I get this: Can't locate TLBC/Report.pm in @INC (@INC contains: /home/glauber/mmtests-0.05-mmtests-0.01/vmr/bin /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /home/glauber/mmtests-0.05-mmtests-0.01/vmr/bin/oprofile_map_events.pl line 11.
