That's what I'm hoping, anyway.

The ebuilds won't be the problem, the ones I need are already in Gentoo 
(and if not, François Bissey, who maintains a Sage overlay for Gentoo, 
has agreed to help me get to know Gentoo).

The summary seems to be (and it's how others have put it as well):
 - Gentoo prefix has the advantage of a much more mature package 
distribution system (and community around it)
 - The ones mentioned has (what is in the community percieved as) the 
advantage of using LD_LIBRARY_PATH (being easily movable, bundleable) 
and using the system compilers and libtool (so they feel less like an 
"OS within an OS" and more like a software distribution mechanism -- one 
could argue this is not a good argument though).

It seems I'm hoping for the best of both worlds, which I might not be 
able to get (or, not without a lot of work, and I guess I should at 
least gain much more Gentoo experience first).
