[Freesurfer] mritotal failed

Hi there,

I am receiving the following error during recon-all:

mritotal -verbose -debug -clobber -modeldir /usr/local/freesurfer/mni/bin/../share/mni_autoreg -protocol icbm transforms/tmp.talairach.7573/src.mnc transforms/talairach.auto.xfm Can't locate shellwords.pl in @INC (@INC contains: /usr/local/freesurfer/mni/bin/../lib/mni_autoreg /usr/local/freesurfer/mni/lib/perl5/5.8.5 /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 /usr/local/freesurfer/mni/bin/mritotal line 460. ERROR: mritotal failed, see transforms/talairach.log

Any ideas?
