 I strongly object to this proposal.

 1. This adds many more gratuitous dependencies to xpdf
 2. The xpdf binaries are silently replaced by poppler binaries.
    That is a dangerous hack.

 Personally, I only really need xpdf, and I require binary
 compatibility of the utilities. I don't want poppler; it's
 deep inside some dependency tree and will hopefully
 disappear from my system someday. If poppler silently
 replaces my xpdf utilities with the wrong version,
 I'm hosed. The resulting critical failures would be very
 difficult to diagnose by someone who doesn't realize
 that the xpdf package is using the proposed hack.

 Note that Debian does something similar to what I
 suggested in my original bug post - xpdf-utils
 is a separate package, also provided by poppler-utils.
 They each provide the utilities and their man pages.
 You can choose either one, independently of whether
 xpdf and/or libpoppler-dev are installed.

 For MacPorts, perhaps the right thing to do is to have
 xpdf-utils and poppler-utils conflict with each other,
 and xpdf and poppler with no further dependency/conflict
 relationships. Or perhaps there is some way to achieve the
 same thing using variants, I don't know how.

 It would be nice if the *-utils packages could be
 built without all of the X dependencies. I have checked
 that this is possible with xpdf - use
 "./configure --without-x"
 I know nothing about poppler.

 Thanks,
 Yitz
