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.
Investigating, it seems that hugetlbfs packages in fedora doesn't
install any perl scripts, unlike SuSE.
I downloaded the library manually, and pointed perl path to it, and it
seems to work.
