thats correct. i wasn't happy about adopting this approach, and i
still find it cumbersome and ugly. it was responsible for the complete
eliminaton of a certain category of bug report, however. that in
itself was a certain kind of validation.

yes, i agree that this is basically what we do already.
the problem is that this doesn't address the person who downloads a
binary package to their machine that is dynamically linked, and who
doesn't know (and has no way to know) that for some reason or another,
the C++ libraries on their machine will cause bizarre problems.
and that's the second part of the two-part problem here:
* binary dynamically linked to (incompatible) libs
* source code compiled and then dynamically linked against
its ensuring that the (incompatible) part is taken care of that is
hard. have you see how many RPM's there are of various libraries out
there? my responsibility, remember, is not just to debian, but to
linux in general. i don't know if there are multiple dpkg's, it seems
less likely ...

right, if we hack up LD_LIBRARY_PATH and put private copies of the
libs in some place (say /usr/local/lib/ardour), then what we've done
is, as you note, just like static linkage, and has no benefits over

this is still private linkage against libraries, which goes against
(as i understand it) debian policy. it violates both security and
resource usage guidelines.

this was before gcc3 emerged. problems started with RH's distribution
of gcc 2.96.
if someone sends me patches that provide configure with options like:
for each library, i will read over them and probably apply them. the
patches should turn off in-tree compilation of the --with'ed
