I didn't misunderstand you, as you will see in later emails I sent on the
Sticking with apache 2.0.x and its apr (0.9) is logical/useful if you desire
WebDAV functionality. (Leaving neon out of the picture for a minute.)
If you leave Apache out of the picture you can use either apr 0.9 or 1.1.
That's my issue. APR 1.1 fixes some bugs, sendfile() use for example, and
supports the OS I am using. I do not want/need WebDAV, others may, and that
difference/issue is what I am trying to solve.

That's what I said, apache 2.0 cannot use apr 1.x. And apache 2.1/2 cannot
use apr 0.9.
Thanks for the clarification on the ABI/API issue, I knew it already, but
perhaps this makes things even more clear for others.

This doesn't solve the case for those who want/need a higher version of apr
for use with subversion and don't need apache/webdav.

2.1 is the step up to 2.2, I guess unstable/development versions are always
explicitly marked with a -dev, if so, yes, than it would mean an
apache2-dev. If not, then apache2 can be 2.1 now and 2.2 when it reaches
the stable point. Of course, one could debate about if you want users to
install 2.1 if it is apache2, since their reasoning might be that apache2 is
newer than apache20 (not quite incorrect), but it is development.
I hope I clarified what I meant.
