Let me rephrase. If a dependency can be bundled then it should be bundled.
The "Linux Way" is to depend on a bunch of random garbage pooped by lord knows bullshit script into one of several global search paths. This is bad, stupid, and wrong. Programs should include as many of their dependencies as is possible.
The number of dependencies that a program can not deploy and must assume are provided by the system are extremely minimal and special case. It's a short and static list.
In general no script or program should add libraries into the global search paths. On Windows user programs do not add random crap to System32. On Linux the existence of /usr/lib is an abomination that should not exist.
Is that better? I'm fairly certain you understand what I'm trying to say.
