and i would recommend that Gentoo never uses --gem-include=bundled, no 
matter the circumstances. this folder is designed for people who want to 
save some time on "manual" downloads and "manual" conf, not something 
automatic for Gentoo. any copy of headers is a tradeoff, as that copy of 
headers risks becoming out-of-sync sooner or later.

the [#to_pix]/[#from_pix] rewrite's best effect, imho, would be to be able 
to make the same gridflow binary run with any gem binary, but in the 
context of pd-extended as a big package, we don't care. in the context of 
a split-package system, though, gridflow may be compiled with gem >= 0.91, 
or 0.90 <= gem < 0.91, or gem < 0.90, and when the choice between the 
three is made, the binary will only run with one of those three 
interfaces, so this has to be taken into account when listing package 
dependencies. (however, those numbers i just listed are perhaps not 
exactly right, especially if people use bêta or alpha versions.)
