After some testing I'm finding it hard to get 2.x DHCP to work
properly, while in 3.x at least a linux client using "dhclient" was
able to get correct response. I'll post more about this in a separate
thread. Would freeradius-user be more appropriate for this?

Sorry, I was trying several build scenarios and forgot to copy the
exact message. Just retried it with

./configure --enable-ltdl-install=no --with-system-libtool
--with-system-libltdl && make

Last few lines of output:

It's there, but enclosed in an #ifdef block. My change:
Not good, but at least it builds. I'm guessing that somehow
WITH_SYSTEM_LTDL was not defined in my original 3.x build.

In case it matters, I use ubuntu natty with libltdl7 2.2.6b-2ubuntu3
and libltdl-dev 2.2.6b-2ubuntu3.

I  cloned https://github.com/alandekok/freeradius-server.git, last
commit was b575b38 : Always use buffer

It's not on https://github.com/alandekok/freeradius-server/tree/master/debian/patches
