No, that's ok, but at this point I think we've covered the subject.  As 
has been pointed out, Derek is welcome to incorporate poppler patches 
into the GPL version of xpdf.  However, just as any 3rd party 
distributor of xpdf (such as Red Hat, for example) can not provide xpdf 
under a different license, Derek can not relicense those patches either. 
  All this is well known to the poppler contributors and to Derek, I'm sure.

Having said that, we are not out to compete with Derek.  The purpose of 
poppler is to provide the xpdf rendering functionality as an easy to use 
library, and change it to better leverage the platform libraries, where 
possible.  If anything this increases exposure and recognition of the 
xpdf code base - we even have a Glyph & Cog plug at the bottom of the 
README.
