Yes, that is exactly what is done (and for the very reason), we just had not
used _that term_ over here for it :-/ though I had seen it used. It is a fair
discriminator esp with shared library dependencies :)

Ok.

This is a fairly stable (upstream) package, it used to be considered big-ish
too as it has all the gtk2 bindings (generated as I recall).
Let me know if I can help. I do not think the package does anything special
on the platform.
