This is nothing to be concerned about. 2.6.38 added a new capability
(CAP_SYSLOG) and deprecated CAP_SYS_ADMIN for accessing syslog. The
warning just means that syslog-ng does not use the new capability yet
(so it works like it did pre-2.6.38). From what I read, it is not
entirely trivial to move syslog-ng over to CAP_SYSLOG (due to wanting
backwards compatibility with kernels before 2.6.38), but they are
working on it.

In short, it is harmless, and the warning will go away in a future
release of syslog-ng.
