I compiled enblend for my mac using macports.  The current portfile uses
the 4.1.2_2 sources from sourceforge.  I made my own version that is
identical but uses the 4.1.3 sources recently posted.  The compile
process was identical for both.  Note that macports does apply a patch
to the configure script to help it find the boost libraries which are
named with '-mt' on the end in macports.

Both of them run configure with the following options (${prefix} here should expand to '/opt/local' for macports):
================================================
configure.args  --disable-split-doc \
                --enable-image-cache \
                --with-boost-filesystem \
                --with-gnuplot=${prefix}/bin/gnuplot \
                --with-openexr
================================================

Here is the output of 'enblend --version --verbose':
================================================

Title:
  White pixels at 180 wrap and zenith for 16/32bit HDR Pano

Status in Enblend:
  New
Status in Hugin - Panorama Tools GUI:
  New

Bug description:
  When stitching my final pano for an HDR workflow I get a column of
  blank/white pixels near the equator at the 180 wrap and an entire row
  of blank/white pixels at the top.  Here's the basic pieces of my
  workflow:

  - Multiple exposures at 7 angles with samyang 8mm + pano head
  - Combined exposures to 7 HDR images using pfstools (sometimes exr files for 16bpp, other times tiff for 32bpp)
  - Use hugin to: mask out pano head arm, find control points, optimize positions, barrel and view and set output options
  - Stitch with a script using nona+enblend to equirec HDR image

  Can view example of the white pixels here:
  - you're facing the 180 wrap when it first comes up
  - zoom in at zenith to see the missing top pixel

  When I look at intermediate files I'm pretty sure it is enblend that is the source of the problem.  I've tried several different versions:
  - The stock version from the OSX binary on the source forge web site (v 4.1.1)
  - Enblend 4.1.2_2 compiled with macports
  - Enblend 4.1.3 compiled with macports (using my own updated portfile to grab the 4.1.3 tar ball)

  All three versions show the same problem.  I'll attach a screenshot
  pointing out the truant pixels as well as a minimal .pto file and the
  script I use for stitching.
