Please read
http://search.cpan.org/~malay/Font-TTFMetrics-0.1/lib/Font/TTFMetrics.pm
(eg 
User of this module should keep in mind that all the values returned
from this modules are in font-units and should be converted to pixel

  fIUnits * pointsize * resolution /(72 * units_per_em)
)

Did you send this message to the Scribus list?? Sorry, but Malay I
don't think is subscribed. See
http://search.cpan.org/~malay/Font-TTFMetrics-0.1/lib/Font/TTFMetrics.pm
for his contact details

You might be better off asking this sort of question on a perl mailing
list. Did you look at line 634 to see what it was trying to do?
