I'm confused.  The only way gpsd can build stuff is if all the
build dependencies are available.  The the two cases are the same.

In the case of the gpsd python, the only time required is a simple macro
subsitution.  Very quick.

I think that is better than not installing, and users complaining. they
can't find it because they did not read and understand the build
warnings.

In the python cases, when something does not work, it is because user
is missing a simple 3rd party package, which is simple to fix.  Plus
the user is told what he is missing only when he tries to run that
program and is focused on that program.

Which is why a runtime warning is better.

To me "install" is into normal system  location.  In Bernie's case
he puts it in a package for users that later "install" on their
system without compiling.

Gonna be a few small python files.  I hate to have a lot of rules or
options.  Either gpsd "installs" it or not.

No time at all.  But the end user needs to do it, or tha package creator
needs to make hard dependencies.  Either way, not time at all.
