Interesting, I got 294 (probably from my local dev tree). Close enough, thanks!
So, taking this count-packages script here:
http://dev.gentoo.org/~dberkholz/scripts/count-packages
And running it, I get the following information about the portage tree
(synced about ~2hrs ago):
Statistics for /usr/portage:
Total packages = 20436
Total categories = 174
Average packages per category = 117
Standard deviation of packages per category = 203
Suggested category size within (standard deviation / 2) of average: 16
to 218
Split categories with more than 218 packages, and do not create
categories with fewer than 16 packages.
Using the total number of packages in the tree against either 285 or 294:
>>> print "%.2f" % ((float(294)/20436) * 100)
1.44
>>> print "%.2f" % ((float(285)/20436) * 100)
1.39
IOW, it looks like less than 1.5% of the tree contains multilib packages
that rely on pkgconfig that could be affected by crossdev installing the
${CHOST}-pkg-config link into PATH.
We all have different measurements of things, but in my book, that doesn't
even begin to qualify for "non-trivial tree-wide problem". If we were
talking close to 5%-10% of packages affected, that to me would be worth some
serious discussion.
So since there isn't a pressing need to do something about it right now,
let's try to think up a proper way to address the problem for the longterm,
because the number of multilib/pkgconfig packages will likely increase in
the future.
Sound fair?
