I updated the v0.9 branch to require LT 2.2.6b to build tarballs, and the trunk to require AC 2.65 (the latest) and LT 2.2.6b.
Libltdl (shipped in libtool) had a security issue that was patched in 2.2.6b. The issue doesn't affect hwloc (hwloc doesn't even use libltdl -- yet), but I didn't want any red flags to be raised because we were using an "insecure" LT version. I took the liberty of updating our AC version on the trunk just for the heckuvit. -- Jeff Squyres jsquy...@cisco.com
