8KB for hello world, checked all its *.so except for libicu(utf-8) it is pretty standard jpeg/png/xml/stdc++ libraries, size does not seem like an issue,

the the GPL license might be of an issue though, then again, the author said he will switch to LGPL in 1.0.0 release, so all is good!

Thanks. Did you strip the binaries?

Not an issue an any OS with a half decent package manager.

How is the quality of the package manager related to the size of the binary?

You can dynamically link and only have to distribute small binaries.
