Pete,

Thanks for confirming.
Yes, I managed to reproduce the problem too.

It was related to some buggy detection of Boost.
The Boost was reported as not detected and set HAVE_BOOST=no
in ./configure but one condition was incorrectly specified,
so compilation flags still included -DHAVE_BOOST=1

I think I've managed to fix it:

I can confirm this line is buggy.
Fixed in the main:

Simply, the [ and ] quoting can not be nested as it was in the old
version of help string. Instead, special "generators" need to be used:
@<:@ for [ and @:>@ for ].


Interesting is that I didn't get any error on Ubuntu 9.04.

I'd be thankful if you could update your copy and test if everything
works now.

Best regards,
