Spider Webs

[James Linder]

Long ago (a week or 2) in a land far away (right here)

X failed to start about 1 in 2 making my ports that use X11 fail to start.
So I upgraded to el Capitan and formatted my disk (case sensitive)
Many ports did work but gnuplot and QT5 failed to build.

So I downgraded and installed yosemite. Everything builds, X always starts, all good except the dear folk who support the ports asked that my tickets include the fail log.

I did have my time machine running (beware if you change from case sensitive to insensitive time machine balks)

Being a sucker for punishment, getting the logs, heeding the ticket advice, I reinstalled el Capitan using time machine.
Everything works and is familiar, but future port builds will not.

If I move /opt/local away, reinstall el Capitan version of macports, build all my ports does the auld /opt/local contain *everything* or are there spider webs related that will make this step a real bad move? DBUS comes to mind.
I’m thinking about future ports and about moving this /opt/local back if I can’t get QT5 to build. 
I can build gnuplot with -aquaterm option.
