AMBER: Leap adds hydrogens but cannot resolve their type.

Hello,

I googled the list archive but could not find this odd topic covered. I'm
trying to create Amber input files using xleap (all AMBER 9.0) for a small
protein domain (33 residues). I have built NAMD inputs for this domain without
any issues but when I try to create AMBER inputs xleap adds hydrogens and then
reports that it cannot resolve the type. Am I missing a standard library? It
seems that the normal ff03 libs are loaded. I would expect a challenge with
non-standard residues/atoms, but this hydrogen issue has me stumped. Ideas?

Thanks,
Paul
