Gary,

Thanks a lot for actually venturing down this path!  Much appreciated!

Darn. That would contradict the FAQ, and explain why we may have stopped at
some point.

That said, some other packages do the dual build with an intermediate
cleaning step.  But that is more work for us, may introduce new bugs, and
we are still not sure if it is really, really needed.

What you suggest does make sense, I just want to make sure we balance costs
and benefits properly.  Could you for example contemplate using a local
package variant that swapped --enable-shared for --enable-static ?  I mean
that more as a hypothetical question -- but it is worth pondering it.

| No such file or directory
| dh_install: command returned error code 256
| make: *** [install-arch] Error 1
| dpkg-buildpackage: failure: debian/rules binary gave error exit status 2

But that's an error at our end we can accomodate. It just needs someone with
spare time and cycles who can try a few builds til it is worked out.
