I agree. The problem is, under some distributions (eg, slackware, or suse),
if /usr/lib/libkstmath.so.1 is installed at build time, it is picked up by the
linker. I can't figure out how to tell the linker to only look in the build
directory for some libraries, and not for others. Interestingly enough, if
the linker links to 2.0.0, then even if the 1.x libraries are later installed,
everything works fine.
This is has actually been a long time problem. If you have kst installed on
your system, and do a build, the linker links to the libraries in /usr/lib,
rather than the ones in the build directory... If we were maintaining binary
compatibility, this wouldn't be a problem for users upgrading - the install
stage would just overwrite the old libraries and no-one would be the wiser.
But it is a pain if you are developing kst on the same machine you are using
it, or if we break binary compatibility, which we do from time to time.
I have seen distributions do this name change hack to get around these sorts
of troubles before, so I think there may not be a clean solution.

My son is hoping to prepare a windows package to go along with the release....
which will be... soon.
