So where is that coming from? I also checked most other libs (libkrb5.so, libgssapi_krb5.so, libheimbase.so, libheimntlm.so, libgssapi_ntlm.so, libgssapi_spnego.so, etc) required with no success. And now I believe I may be officially out of my depth, as this seems to be a path order issue in the linking process. Anyone shed some light here?
