    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.
