That was more or less the conclusion I'd come to and that is a semi nightmare to craft by hand.

Knowing I'm not the only person to have this sort of issue, I was hoping for something like Richards setup.  I'll have a look and tweak it to fit Calibre 3.

Oddly, the custom built elements of Calibre 3 demanding this, run elsewhere, built normally, on this system with the older glibc.

I've seen it before.  it starts out broken.  get's a "won't fix" and then down the road, somehow it's silently fixed.

sigh  more wasted time
