thats a bug in checkinstall. if you run scons install, that will not
happen.

its not a problem with the system libs. its a problem when some
unknowing user, for whatever reason, installs a new version of g++ and
rebuilds either ardour or the affected libraries, but not both. bizarre
behaviour ensues, we waste hours or days tracking it down, only to find
that its another problem with mismatching g++ issues. it doesn't even
need that - at least one distro built some of its c++ libraries so that
they didn't use exceptions, which then breaks other c++ code.

we dealt with this years ago by deciding to include every c++ library
that ardour uses in the source tree, except those that actually come
with the compiler. 

we did not sanction the use of SYSLIBS=1 for ardour 0.99.3, and we will
not sanction it for any version in the future.
