Bug#459712: build-conflicts with its own runtime

[Faidon Liambotis]

[the following is a more useful description of the bug than the irc log]

pwlib and pwlib-titan build-conflict with their runtime parts besides 
the -dev parts.
I think this is being done because a sample program is built and run 
when the package builds as a mean to catch runtime errors/screwups early.

I'm not sure, however, if the conflict is really needed.

The current situation is bad because people trying to do build tests on 
their desktops have to uninstall ekiga among others.

Kilian, you've added both the conflicts and the sample build/run.
Have you investigated if the conflicts is needed?

In the case that it is, how would you feel about making the sample 
build/run conditional on the presence of libpt in the build system?

Thanks,
Faidon
