mpkg fails to include certain component packages

[ctreleaven (Craig Treleaven)]

The mpkg for mythtv.28 fails to include certain certain components. The missing components all have a non-zero epoch.

I suspect a recent commit [1] is related but I'm not fluent enough in TCL to be sure.

Steps:

It has been 4 months since I last built an mpkg installer for mythtv.28. The new installer appeared to build successfully but was 40 ro 50 MB smaller than expected. On testing an install, Installer reported an error (log attached) that it could not locate the package gettext.

Jan 16 20:29:55 MacMyths-Mac Installer[493]: Failed to locate package at path /Volumes/Clooney/Test_installers/gettext-2_0.19.8.1-component.pkg (gettext-2_0.19.8.1-component.pkg -- file://localhost/Volumes/Clooney/Test_installers/mythtv.28-0.28-Fixes-20161227.mpkg)

I used pkgutil --expand to check the contents of the mpkg. The included Distribution file showed the lines for gettext were malformed as were several others. These included libedit, openssl, python27 and others. After noticing that each of these had a non-zero epoch, I verified that all such dependencies were failing to be included. Viz:

port info  --name --epoch --line rdepof:mythtv.28

Note that I'm running MacPorts master. I've taken the liberty of copying jmr.
