Phew ... thanks Leighton for that detailed summary. I'll go through and see
whether I can ease a few things (if I find out out, that is).

Too old? Oh dear, what do they install in CentOS?

Argh, the old flex vs flex++ nemesis. If only I know how to correctly check for
this kind of interesting installations. Fortunately that does not happen all
too often.

Yes ... I am relying on the autoconf BOOST macros and they are also really,
really difficult to understand. When they work, everything's perfect. But when
they don't, wrapping one's head around what they might be doing and why they
fail ... well, I've given up. BTW, the amount of debugging output related to
BOOST in the configure.in script gives a hint on the amount of work I already
put into it :-/

This mailing list also exists for exactly that reason: allowing people to find
it via Google when they have a problem ... and find a solution. Thank you for
the detailed account ... at least for flex++ I think I might have a silution.
