I read a webpost that talked of qt-creator using it's own version of
botan hence I didn't think it would be a linking error, that it would
have the correct stuff "on board". A viewing of the ebuild shows that it
has a USE_SYSTEM_BOTAN=1 so I reinstalled botan, even though I already
had the latest version installed, and hey presto, it built.
Thanks for the comments,
