I believe I read Nathan mention how this was a rarity (only in AIX, right?)--
but are there any plans to make the new libpthread dynamic-capable?
The killer is when libpthread is bumped, pkgsrc-linked code must be updated
manually, in multiple dependency trees (for a large set of installed
packages). You gotta just guess what links to pthread now. This was a bit
more manageable with devel/pth, as you could walk away from a 'make update'
and know you'd be coming back to new code.
Perhaps we can we create a meta-pkg (devel/nbsd-pth?) that will simply check
for a new version in /usr/lib and initiate a 'make update' for dependent
packages? This would imply setting up nbsd-pth as an either-or to GNU pth,
which is probably not a great idea.
Perhaps a better idea is to patch our GNU pth to defer to the in-tree pthread
if it exists, and we can keep devel/pth as a dependency.
At present, it sure makes it *tough* to debug Alpha userland; as by the time I
start to get meaningful debug data on e.g. mozilla-- pthread has a slough of
new code in it, which can affect any one of a number of its dependencies.
