Blast. Sorry about that; can you send a pointer to your patches? I seem to recall that we were amenable to some of the changes, but not all of them.

...looking through the SVN commit logs, we did commit *some* BSD-related things to the v1.4 tree. For example:

These fixes where what I was referring to in the changelog.

Additionally, I just put some work in the development trunk that adds support for a new embedded software support library (hwloc), but, based on feedback from you and others, it allows you to configure one of 3 ways:

 * Use the embedded hwloc
 * Use an external hwloc installation
 * Don't compile hwloc at all

I plan on extending this technique to libltdl, which should hopefully obviate at least some of your patches.
